Existing efficient macro/plugin for transposing stack/hyperstack
 
|
Dear Imagers,
I’m looking for existing code that will take an AxB stack/hyperstack and transpose its entries to a BxA hyperstack. This is useful if a large 4d dataset is already in an A time points of a single focal plane x B focal planes format, but should be in a B focal planes x A time points per focal format. If the code works on a large stack that can be read in as a Virtual Stack, that would be awesome (my example is a QuickTime movie that has 8100 frames).

I don't think that connected dots would make much sense (the line would hide the dots). One could think of connected boxes or diamonds [oops, I just see that we even don't have plain diamonds yet!] Beyond ImageJ, I have seen much more plots with connected circles compared to other connected symbols, so I consider this not too bad a choice. Also, the CONNECTED_CIRCLES are still not as nice as those of some other plotting programs; I think it would be nicer to have the lines end just outside the circles, not go all the way to the centers (if I have much time, maybe I'll change this). But what we have is better than nothing. If you want, e.g., connected squares, you could plot the same data set twice, once as squares (BOX), then as a line. In any case, ImageJ is not a full-fledged plotting program; if you need advanced plots you will still need Gnuplot, Grace, Veusz, etc, or the expensive solution named Origin.

A second question is how to use the labels that are in the last argument of the addPoints command. I would like to put them in the legend, but I do not see how to recover them in order to add them to the addLegend command.

Is there any command, which moves the displayed are to specified coordinates?

Detailed information is below. Digital Image Analysis with ImageJ November 7th – 9th 2017 This intensive 3-day workshop taught by Dr. Lai Ding, Senior Imaging Scientist of the NeuroTechnology Studio(formerly manager of the Harvard NeuroDiscovery Center Enhanced Neuroimaging Core), introduces ImageJ, its basic functions, and its macro programming capabilities. Using real imaging projects, Dr. Ding will demonstrate common image analysis tasks such as basic image processing, stack alignment, cell counting and measurement. Macro writing will be covered to demonstrate how to automate a series of ImageJ commands, to process massive datasets automatically and to store results as desired. The workshop is broken down into three sessions. Interested participants can sign up for one or more sessions depending on their interest and experience. See tentative schedule below. If you are interested in this workshop but unable to join this time, please also let us know (email [hidden email]<mailto:[hidden email]>) if you may be able to join the same workshop in the coming months. We MAY host another identical workshop in near future based on the interests shown. ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- Program Schedule: Session I (November 7th ) ImageJ for beginners: basic ImageJ functions, measurement, filtering, background subtraction, cell counting, particle analysis, and ethics on image processing. Session II (November 8th ) Advanced ImageJ: morphology filter, thresholding methods, using ImageJ on FRAP, colocalization analysis and wound assay, working with plugins, designing image analysis protocols. Session III (November 9th ) ImageJ Macro Programming: introduce ImageJ macro programming language, record image process protocols as macro, batch process multiple images, user interactive features in macro, case study with sample codes. This session is aimed towards the non-programmer, however we do expect the participant to have a basic idea of programming flow control syntax ("for" loop, "if-else" control). The participants are strongly encouraged to go through a brief tutorial on the ImageJ official website before the workshop. http://rsb.info.nih.gov/ij/developer/macro/macros.html Workshop Location: L2-025 Countway Library Computer Classroom Harvard Medical School 10 Shattuck St. Boston, MA 02115 To register, please complete the online registration form by clicking https://docs.google.com/forms/d/1n3n5tzSR_MM45NqkF1gW4JTa2SfhnaKNEkrry0H5X7o/ For further information please contact: Lai Ding at [hidden email] Best Regards Lai Ding -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html ------------------------------ Date: Mon, 18 Sep 2017 23:04:26 -0400 From: Fred <[hidden email]> Subject: ImageJ Compile&Run compiles java program in editor but runs from cache.

Hi Daniel and Bene, I realize this is an old post, but I was wondering if either of you ever got Amira to work with segmentation editor. I am interested in doing exactly what Daniel has proposed: to save and load a current segmentation or even save a finalized segmentation so that I can analyze or reanalyze it at a later time (in 3D ROI manager). Thus far, I am able to save the labels (as a tiff file), which is basically the black screen with my labeled segments, but I am not able to merge it with the actual file that was segmented (the file that has my brain image). I have downloaded the Amira reader and writer plugins to save my segmentation progress, but Segmentation Editor doesn't seem to recognize the loaded file. Do either of you have any idea as to what I am doing wrong. Thanks so much in advance for your insight!

How to fix? Hi Fred, in my experience, 'Compile&Run' recompiles source files that are newer than the corresponding .class files. This is true for all classes that are called from the main class (the one you select with 'Compile&Run'), not recursively for others. So if you have My_Plugin, calling SubClass1, calling SubClass2 and My_Plugin has no reference to SubClass2, then ImageJ won't compile SubClass2, even if SubClass2.java is newer than SubClass2.class. To make sure, just delete all .class files, then ImageJ will recompile all.

The problem existed after and no other changes have been made, except to the source code of the plugin in question. The plugin recompiles, timestamps of the class files and java files are when I hit Ctrl-R. As tests, I inserted a syntax error into the source, hit Ctrl-R, and the error window pops up correctly identifying the syntax error; I erased the .class files while imagej is running and ran the plugin from the Plugins menu and the version that existed when imagej started was run; *without the .class files in the plugins directory*. This leads me to believe that there is a cache somewhere; which I can not find. When I start imagej with the .class files in the plugins directory the .class files seem to get placed in some cache somewhere, once they are there they do not get updated. Running the Help->Refresh Menus with the .class files cached the version that runs is not updated. As a new test I tried, exiting imagej, erase .class files, start imagej; the plugin does not show up in the Plugins menu; then I update the plugin, i.e., change a string in a IJ.log, Ctrl-R, Help->Refresh Menus; the plugin now shows up in the Plugins menu and it runs the current version. Make another update, Ctrl-R, and it runs the previous version.

Thanks in advance for any help on these issues. --aryeh -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html ------------------------------ Date: Mon, 18 Sep 2017 09:50:20 +0200 From: Michael Schmid <[hidden email]<mailto:[hidden email]>> Subject: Re: move displayed area to find a marker Hi Csaba, here is a simple macro that takes a point selection with several points and zooms on each of them, one after the other, each time you press the F8 key.

Is there any command, which moves the displayed are to specified coordinates? It would be extremely useful if i could jump from one ROI location to the next one without zooming out and zooming in again.Csaba -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html ------------------------------ Date: Tue, 19 Sep 2017 10:49:42 -0400 From: Lai Ding <[hidden email]<mailto:[hidden email]>> Subject: Announcement: Digital Image Analysis with ImageJ Workshop Nov 7/8/9 Dear Everyone, The NeuroTechnology Studio at BWH will host a 3-day ImageJ workshop in November 2017. Detailed information is below. Digital Image Analysis with ImageJ November 7th – 9th 2017 This intensive 3-day workshop taught by Dr. Lai Ding, Senior Imaging Scientist of the NeuroTechnology Studio(formerly manager of the Harvard NeuroDiscovery Center Enhanced Neuroimaging Core), introduces ImageJ, its basic functions, and its macro programming capabilities. Using real imaging projects, Dr. Ding will demonstrate common image analysis tasks such as basic image processing, stack alignment, cell counting and measurement. Macro writing will be covered to demonstrate how to automate a series of ImageJ commands, to process massive datasets automatically and to store results as desired. The workshop is broken down into three sessions. Interested participants can sign up for one or more sessions depending on their interest and experience. See tentative schedule below. If you are interested in this workshop but unable to join this time, please also let us know (email [hidden email]<mailto:[hidden email]>) if you may be able to join the same workshop in the coming months. We MAY host another identical workshop in near future based on the interests shown. ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- Program Schedule: Session I (November 7th ) ImageJ for beginners: basic ImageJ functions, measurement, filtering, background subtraction, cell counting, particle analysis, and ethics on image processing. Session II (November 8th ) Advanced ImageJ: morphology filter, thresholding methods, using ImageJ on FRAP, colocalization analysis and wound assay, working with plugins, designing image analysis protocols. Session III (November 9th ) ImageJ Macro Programming: introduce ImageJ macro programming language, record image process protocols as macro, batch process multiple images, user interactive features in macro, case study with sample codes. This session is aimed towards the non-programmer, however we do expect the participant to have a basic idea of programming flow control syntax ("for" loop, "if-else" control). The participants are strongly encouraged to go through a brief tutorial on the ImageJ official website before the workshop. http://rsb.info.nih.gov/ij/developer/macro/macros.html Workshop Location: L2-025 Countway Library Computer Classroom Harvard Medical School 10 Shattuck St. Boston, MA 02115 To register, please complete the online registration form by clicking https://docs.google.com/forms/d/1n3n5tzSR_MM45NqkF1gW4JTa2SfhnaKNEkrry0H5X7o/ For further information please contact: Lai Ding at [hidden email] Best Regards Lai Ding -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html ------------------------------ Date: Mon, 18 Sep 2017 23:04:26 -0400 From: Fred <[hidden email]> Subject: ImageJ Compile&Run compiles java program in editor but runs from cache.

Hi Daniel and Bene, I realize this is an old post, but I was wondering if either of you ever got Amira to work with segmentation editor. I am interested in doing exactly what Daniel has proposed: to save and load a current segmentation or even save a finalized segmentation so that I can analyze or reanalyze it at a later time (in 3D ROI manager). Thus far, I am able to save the labels (as a tiff file), which is basically the black screen with my labeled segments, but I am not able to merge it with the actual file that was segmented (the file that has my brain image). I have downloaded the Amira reader and writer plugins to save my segmentation progress, but Segmentation Editor doesn't seem to recognize the loaded file. Do either of you have any idea as to what I am doing wrong. Thanks so much in advance for your insight!

How to fix? Hi Fred, in my experience, 'Compile&Run' recompiles source files that are newer than the corresponding .class files. This is true for all classes that are called from the main class (the one you select with 'Compile&Run'), not recursively for others. So if you have My_Plugin, calling SubClass1, calling SubClass2 and My_Plugin has no reference to SubClass2, then ImageJ won't compile SubClass2, even if SubClass2.java is newer than SubClass2.class. To make sure, just delete all .class files, then ImageJ will recompile all.

How to fix? Greetings Gabriel, There is only one copy of ImageJ. The problem did not exist before I killed imagej while it was stuck. The problem existed after and no other changes have been made, except to the source code of the plugin in question. The plugin recompiles, timestamps of the class files and java files are when I hit Ctrl-R. As tests, I inserted a syntax error into the source, hit Ctrl-R, and the error window pops up correctly identifying the syntax error; I erased the .class files while imagej is running and ran the plugin from the Plugins menu and the version that existed when imagej started was run; *without the .class files in the plugins directory*. This leads me to believe that there is a cache somewhere; which I can not find. When I start imagej with the .class files in the plugins directory the .class files seem to get placed in some cache somewhere, once they are there they do not get updated. Running the Help->Refresh Menus with the .class files cached the version that runs is not updated. As a new test I tried, exiting imagej, erase .class files, start imagej; the plugin does not show up in the Plugins menu; then I update the plugin, i.e., change a string in a IJ.log, Ctrl-R, Help->Refresh Menus; the plugin now shows up in the Plugins menu and it Help->runs the current version. Make another update, Ctrl-R, and it runs the previous version.

I read a little imagej code and came upon: /** This version of the constructor is used when ImageJ is launched using Java WebStart. */ public PluginClassLoader(String path, boolean callSuper) { super(new URL[0], Thread.currentThread().getContextClassLoader()); init(path); } Which seems like it might be using a cache class loader if 'Java WebStart' is turned on.
