I am a new SNAP user and I would like to perform GLCM (Grey Level Co-occurrence Matrix) on some high-resolution SAR data using custom window size values, i.e., not necessarily the ones listed in the Parameter panel (5x5, 7x7, 9x9, 11x11). I created a .xml file with the GLCM parameters used within the GLCM module and set a 21x21 window size as a test (see attachment).
Then, in “File” I selected the option “Load Parameters” to import my .xml file and related parameter settings. However, SNAP returns the following error message:
Everything seems working fine if the window size is set as one of the values in the list, i.e., 5x5, 7x7, 9x9, 11x11. Am I doing anything wrong? Could anyone support with this please, or is there any way to change the default window size values in the source code?
I am working with a macOS Monterey, Version 12.4 and I am running the latest major version 8.0 of SNAP, all updated.
I have the same problem and tried to find the GLCM source code in the SNAP directories; however, I was not able to change the source code to input different window sizes rather than the default ones.
@marpet, @ABraun, It would be appreciated if you can help me to find a way to use larger window sizes than the default ones when running texture analysis module in SNAP.
Dear @marpet and @jun_lu thanks a lot for your support on this! Currently, anything different from 5x5, 7x7, 9x9 and 11x11 is not working for me, including the 17x17 mentioned by @marpet.
