SNAP - StaMPS Workflow Documentation

really not but it intersects two of IW (1 & 2) and from the other one image of IW2. Here is the screen shoot of my study area

as this is probably descending data, have you checked if there is time-series ascending track which fully covers this area within one sub-swath?

I was trying to get it but there is no full time series data as I want to proceed it. This is the fileting criteria

there is any ascending data from 2018 until now. There is no search result what I found from the area.

you’re right - ascending data is only available until 2017 in this area.

so what am suppose to do? what is your suggestions ? thank you in advance.

according to this comment, you can merge all interferogram pairs (and stacks) before using the StaMPS export:

Dear all,
at first i would to thank you for all help I got from you. but I am still need help. when i turned stamps in Matlab I got the following error Can somebody to advise me .

STAMPS: ########################################
STAMPS: ################ Step 5 ################
STAMPS: ########################################
STAMPS: Directory is PATCH_6

PS_CORRECT_PHASE: Starting
Correcting phase for look angle error…
GETPARM: small_baseline_flag=‘n’
PS_CORRECT_PHASE: Finished
Error using movefile
Text file busy

Error in stamps (line 462)
movefile(‘patch.list’,‘patch.list_old’);

maybe this file is currently opened in matlab?

I recommend to close matlab and make sure that none of the files is currently selected or accessed by another process and then start step 6 again.

Hallo,
I did it and i got other errors so as:
tamps(6,6)

is there someone who had the same errors before?
I need help.

are snaphu and triangle installed correctly?

oh yes

according to this topic the files were not written in all patches. How many Patch directories do you have? How many did you select in the mt_prep_snap command?
Please check if files are in the PATCH folders. If they are not filled with data, please repeat steps 1 to 5 in the top folder of your directory (containing all PATCH folders)

Also, are you processing PSI or SBAS?

I am processing PSI. I did " mt_prep_snap 20200107 /media/sf_INSAR_20200107_data/ 0.4 3 2 50 200" and i got 6 patches. All 6 patches are full. each patche is 34 items and the size is little bit different for patch 6 , hij 564.9 MB , patche 5 is 575,7 MB and so on .

sounds all correct to me.
is psver.mat in every patch?

yes he is in all paches with th same size of 176 bytes

I don’t know then, sorry.

Maybe you move the PATCH files to another directory and run all steps again, starting from 1

ok i wil try again. thank you

For matlab running on linux,

could be that matlab is out of memory, permission/ownership problems, or a foreign filesystem.

matlab is running under ubuntu, and the errors are :slight_smile:
