So it is the same as here?

Error unwrapped phase Interferometry

Hello! I process two images to build a displacement map. For the merger of IW2 and IW3, I erased the TOPS Merge function, but when I start the unwrapped phase in Cygwin, I get an error “27 parameters input from file snaphu.conf (84 lines total) extra data in file Phase_ifg_srp_IW1_VV_09May2015_05Nov2015.snaphu.img (bad linelength?)” Why? Is this error related to the Merge function?

One solution was proposed here

Snaphu Export Interferometry

SRP (Subtract Reference Phase) is after producing the interferogram and you have subtracted the phase Earth phase. SRD (Subtract Reference DEM) is after topographic phase removal. The band dimensions should be the same either way. I think the bad linelength error may be related to passing snaphu a wrong dimension. Double check that the snaphu command in teh snaphu.conf file corresponds to this product and the dimensions are the same as the band.

Does the snaphu command really address the correct file?
