When pressing OK after filling in the details in ‘generating multispectral image’ a error message appears saying:
File open error:
“/applikations/ImageJ.app/plugins/micaToolbox/importSettings.txt (No such file or directory) in line 218
dataFile = File . Open ( settingsFilePath<)>;
First, try removing the “.” in the ImageJ path (i.e. rename “ImageJ.app” to “ImageJ” or similar).
Next, try deleting the existing “importSettings.txt” file (it will make a new one).
Then, it’s possible the imageJ installation directory has some kind of read/write access blocked. So try moving the ImageJ folder somewhere else (away from system-protected areas).
Do let me know which of these (if any) solve your issue.
