Save values & Popup window

Hi,
Last time I was helped very well, so I hope someone can help me again. I have an image which I threshold manually. Afterwards I want to save the minimal and maximal value of this threshold to a textfile. This is done two times, so if the text file could be updated, that would be great. Underneath you find my code so far. First I want to create a textfile where I can save my values. Then I want to print the text 'Minimal threshold' plus its value. However, it creates the text file, but does not print any text in it. Is there a way to print the text in the textfile and update it with the maximal threshold? run("Threshold..."); waitForUser("set the threshold and press OK, or cancel to exit macro"); getThreshold(lower,upper) print("your thresholds are; "+lower, "to "+ upper); file=File.open(Output+threshold.txt) open(file) print(file, "Minimal threshold"+lower+"\n"); Next to that, I would like to have a pop-up screen where some can select a value that will be used in another calculation. I found that Dialog.create could be used for this. However, normally codes like Dialog.create will change from black to a yellow collor when there typed right. With Dialog.create this does not happen and also does not show any pop-up screen when an option with Dialog.addChoice is included. Thank you already. Iris |

Good day Iris,
evidently this is a cross post from the forum. Here is the first part of my answer: waitForUser("set the threshold and press OK, or cancel to exit macro"); getThreshold(lower,upper); // missing ";" print("your thresholds are; " + lower + " to "+ upper); // corrected Do you recognize the syntax error? second part in some minutes Best Herbie :::::::::::::::::::::::::::::::::::::: Am 24.10.16 um 16:11 schrieb Ihiertje: > Hi, > > Last time I was helped very well, so I hope someone can help me again. > I have an image which I threshold manually.

In reply to this post by Ihiertje
Iris,
this is part 2 of my answer. Here is the macro code: ///////////////////////////////// waitForUser("set the threshold and press OK, or cancel to exit macro"); getThreshold( lower, upper ); print("your thresholds are: " + lower + " to "+ upper ); txt_file = File.open( "Thresholds.txt" ); print( txt_file, "Minimum threshold: " + lower + "\n" ); print( txt_file, "Maximum threshold: " + upper ); ///////////////////////////////// getNumber( "Minimum", lower ); Does the latter help with your last question?

Hi Herbie, Thank you for your effert and time. Unfortunately my code is not working yet. The textfile thresholds is made, however in de debug screen it is stored as follows: file ="~0~". So it won't recognizes where it is stored I think. This is also the reason I think that nothing gets printed in it. When running this part of the code no error is given. file=File.open(Output+"Thresholds.txt") print(file, "Minimum threshold: "+lower + "\n") Do you maybe have an idea how to solve this? Thanks a lot. Iris 2016-10-24 17:10 GMT+02:00 Herbie [via ImageJ] <[hidden email]>: Iris, |

Good day Iris,
if you look at <https://imagej.nih.gov/ij/developer/macro/functions.html> you will find the following: "File.open(path) Creates a new text file and returns a file variable that refers to it. To write to the file, pass the file variable to the print function. Displays a file save dialog box if path is an empty string. The file is closed when the macro exits. Currently, only one file can be open at a time. For an example, refer to the SaveTextFileDemo macro." With this information you may either pass an empty string as path which brings up a file dialog or you enter a correct path. I don't know whether Output+"Thresholds.txt" is a correct path because you do not specify Output in your code snippet. I've simply used "Thresholds.txt" which means that the file is stored in the ImageJ directory. The text file definitely contains: Minimum threshold: <min_val> Maximum threshold: <max_val> I don't understand what goes wrong on your side. Please try to run the code I've provided without any changes and perhaps use txt_file = File.open( "" ); instead. Good luck Herbie :::::::::::::::::::::::::::::::::::: Am 25.10.16 um 08:47 schrieb Ihiertje: > Hi Herbie, > > Thank you for your effert and time.

Hi Herbie, I used your code this time. Last time I did not now where the Threshold file would be saved. It still creates the text file, however, no data is saved in it. Also no error is given by ImageJ. Could it maybe be due to an update or something? It is strange that is does not work with me. Kind regards, Iris 2016-10-25 11:47 GMT+02:00 Herbie [via ImageJ] <[hidden email]>: Good day Iris, |

Iris,
as I said, the posted macro works for me. The text file is written and it contains the data. Did you wait until the macro finishes? Please try again with: ///////////////////////////// waitForUser("set the threshold and press OK, or cancel to exit macro"); getThreshold( lower, upper ); txt_file = File.open( "Thresholds.txt" ); print( txt_file, "Minimum threshold: " + lower + "\n" ); print( txt_file, "Maximum threshold: " + upper ); File.close( txt_file ); exit(); ///////////////////////////// Best Herbie :::::::::::::::::::::::::::::::::::::: Am 25.10.16 um 13:02 schrieb Ihiertje: > Hi Herbie, > > I used your code this time.

Hi Herbie, It is working now! Thank you very much. I think one of the problems was the most simple one. I had an error at the end of my code, therefore never I did not finish the macro. I think this was the biggest bug in the end. Thank again for your help. Iris 2016-10-25 13:10 GMT+02:00 Herbie [via ImageJ] <[hidden email]>: Iris, |
