API way to do deinterleave?
Locked
 
|
I need to deinterleave a stack, and this is how I currently do it.
IJ.run(imp ,"Properties...", "channels=1 slices=1 frames="+str(timePoints)+" unit=pixel pixel_width=1.0000 pixel_height=1.0000 voxel_depth=1.0000") and this works fine. However, when IJ.run() commands open up window, I need to get a handle on those windows, and this requires knowing the names or id's of the windows that were opened. This is ok, but awkward, especially when more than one image windows is generated. Also, it means that the images are displayed, which is not always needed or desirable. In this case, I deinterleave nine fields,so it is awkward. So I close all image windows before deinterleaving, and then grab the entire image list and create a list of ImagPlus objects. Is there a stack deinterleave method (similar to reduce() and some other stack methods), that can be called and will return a list of the deinterleaved images. I can duplicate, reduce(), remove an image and repeat, but I am hoping that I do not have to reinvent it. tnx in advance --aryeh -- Aryeh Weiss Faculty of Engineering Bar Ilan University Ramat Gan 52900 Israel Ph: 972-3-5317638 FAX: 972-3-7384051 -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html |

Hi Wayne
Thank you for your reply. I made a mistake below, copying the wrong line. I meant the following: IJ.run("Deinterleave", "how="+str(fields)) which is the same as Image>Stacks>Tools>Deinterleave... And in my case, the argument fields will equal 9, so 9 stacks will be created from the original stack. So I am looking for the Deinterleave method in the API, if it is available.

Good day Aryeh,
AFAIK, "Stack_Interleaver"-plugin is not part of ImageJ but comes with Fiji. My version of this plugin shows the following header information: //@author J. Anthony Parker, MD PhD //@version 20September2001 The plugin can be downloaded from: <http://www.med.harvard.edu/JPNM/ij/plugins/StackInterleaver.html> HTH Herbie ::::::::::::::::::::::::::::::::::::::::: Am 13.09.18 um 04:16 schrieb Aryeh Weiss: > Hi Wayne > > Thank you for your reply. > I made a mistake below, copying the wrong line.

The Deinterleave plugin in Fiji (Image>Stacks>Deinterleave) does not have an API for splitting a stack into sub-stacks but ImageJ's built in ChannelSplitter plugin (Image>Color>Split Channels) does. Here is a JavaScript example that splits a 36 slice stack into nine sub-stacks: imp = IJ.createImage("Untitled", "8-bit noise", 256, 256, 36); imp2 = HyperStackConverter.toHyperStack(imp,9,4,1,”default”,"Grayscale"); subStacks = ChannelSplitter.split(imp2); for (i=0; i<subStacks.length; i++) print(subStacks[i]); -wayne > I can duplicate, reduce(), remove an image and repeat, but I am hoping that I do not have to reinvent it. > > tnx in advance > --aryeh -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html |

First of thanks to Wayne, Herbie and Jan who replied, each with good
suggestions. I apologize to my delay in replying, but I had a few very hectic days (Wayne previously sent his solution to me offline), The idea to create a multichannel hyperstack and then split the channels is just brilliant. This list is amazing.
