Could you check the size of the unwrapped interferogram from two snaphu runs? Are they the same size?

Checked. The same size.

Checked. The same size.
May I ask how many bytes are they?

@hfattahi, As Scott wrote in https://github.com/isce-framework/fringe/issues/21#issuecomment-883757903, this could be a wrong width issue. Is it an issue in my script for make xml and vrt files in this case? However, I successfully checked it on data from the built-in snaphu also. My script code:

def cmdLineParser(): ''' Command line parser. '''
parser = argparse.ArgumentParser(description = 'Make metafiles for external unwrapped data',
formatter_class=argparse.ArgumentDefaultsHelpFormatter)
parser.add_argument('-i', '--unwrap_file', type=str, dest='unwrapFile',
required=True, help='input unwrapped file')
parser.add_argument('-m', '--metadata file', type=str, dest='interferogramFile',
required=True, help='Input interferogram file for existing metadata')
return parser.parse_args()
def write_xml(fileName,width,length,bands,dataType,scheme):
img = isceobj.createImage()
img.setFilename(fileName)
img.setWidth(width)
img.setLength(length)
img.setAccessMode('READ')
img.bands = bands
img.dataType = dataType
img.scheme = scheme
img.renderHdr()
img.renderVRT()

ds = None
return length, width

inps = cmdLineParser()
length, width = getSize(inps.interferogramFile)
print("length, width: ", length , " ", width)
write_xml(inps.unwrapFile, width, length, 2 , "FLOAT", "BIL")
# uncomment if you need to generate xml and vrt for conncomp
# write_xml(inps.unwrapFile+'.conncomp', width, length, 1, "BYTE", "BIP")

Thanks for checking the size. Obviously they are identical.

Your script looks fine to me. Have you checked what is written differently to your "20200505_20200809.unw.xml" between the two runs?

Сhecked, but everything is the same.

Here only path differ [insar@osllnx07 unw]$ diff -s /data/insar/Proc/merged/fringe/PS_DS/old/20200505_20200809.unw.xml /data/insar/Proc/merged/fringe/PS_DS/unw/20200505_20200809.unw.xml 80c80 /data/insar/Proc/merged/fringe/PS_DS/old/20200505_20200809.unw

Solved. Need to specify width instead of length in snaphu string in my case. @hfattahi Do i need include script to the master branch?
Hi Has anyone tried using the non built-in snaphu for imports into mintpy? I processed the interferograms with the latest version of snaphu (2.0.4) but got an corrupted images. Used snaphu (tested with/without tile mode) + make xml and vrt with custom script from isce2 pkgs. The images processed with build-in snaphu from isce2 packages looks correct. Playing with different snaphu options (data formats, uwrapping modes etc) with no effect.
