hi, I've encountered this error before. I believe you should rename *.LED and *.PRM files like this : 20210110.LED, 20210110.PRM and so on

Hi, I was renamed files like 20210110.LED, 20210110.PRM after i ran prep_gmtsar.py i got the new error

[soroushyasini]

I did not know this issue since I've never encountered it. but i think perhaps it's related to the config file. can you provide me the config file specially the part for setting GMTSAR data path ?

[soroushyasini]

also we can check baseline.txt file, can you provide one of them here ?

[laxmangeo]

yes you are right , this issue from baseline.txt , i solved it , but TypeError: Can't broadcast (410, 350) -> (390, 330)

[soroushyasini]

happy to see that you solve them and yet here are new problems to solve :) this issue is exactly the same issue I am struggling with it , check this link below :

https://github.com/gmtsar/gmtsar/issues/921

i checked each unwrap_ll and corr_ll files that GMTSAR created, they are slightly different in term of pixel size and X,Y dimension. and that is why Mintpy can not make a array of rasters since it need same-sized rasters as input. as far as i know, the problem is because of GMTSAR and not for Mintpy. by the way, i am glad if you find any solution and share it to me.

have you used any region cut at the time of unwrapping? in my case I did that, Now I tried region cut at the generation of interferograms ( batch_tops.config file), problem was solved.

[soroushyasini]

no i did not cut them. interesting... so did you cut by lat/long or by radar coordinates ? and second question, how did you run gmtsar? i mean did you use batch_processing.csh ?

[laxmangeo]

I cut in radar coordinates, I'm using batch_processing.csh

[soroushyasini]

ok I got it, thanks for your help. i guess this issue can be closed as Completed.
