ERROR step2

[崇佑王]

Deal all,

i meet an error like the following:

                    ps_est_gamma_quick(est_gamma_parm);

it has a similar issue in the group, which is caused by NAN.(https://groups.google.com/forum/#!searchin/mainsar/Subscript$20indices$20must$20either$20be$20real$20positive$20integers$20or$20logicals.%7Csort:date/mainsar/abhtaJk_mIg/q_oqjq9SEAAJ)

However, there don't have NAN after i checked. And it see someone say that it has updated script for this problem, but i also failed even if i updated the ps_es_gamma_qucik.m .

By the way, it was successful for other patches and i use isce instead of snap.

Does anyone know how to solve that? Thanks a lot!

I think you should use newer version of Stamps available on github

I had updated stamps, however, it still failed.

i find "mt_extract_cands" is th problem because pscands.1.ll and pscands.1.ph are full of zero in some specific patch.

does anyone know how to solve that?

Hi kevin

Have you solved this problem？

[kevin112...@nctu.edu.tw]

Hello raincxy,

Sorry for responding late. I solve this problem. The problem derived from the step mt_prep_isce, which happens when the study area is big. Have you solved this problem ? If you have not solved, I can tell you what codes should be revised.

Unfortunately, I still haven't solved the problem.I guess there may be something wrong with the operation in the previous step, but I don't know how to change the code, so I can only keep changing the number of patches.

  I have processed the stamps(5,5) and did not receive any error message. But after running this fifth step in matlab, all the patches should merge together and a separate folder 'MERGE" should also create in the same directory. This merge folder is not created in my case after running the fifth step. Can anybody help me in this regard?
