Error in stmaps(1,1) for gamma2stamps

I use GAMMA for preprocessing, and then run stamps (1,1). The following error occurs. How can I solve it?

error message: master_ix=sum(day<master_day)+1;

Just enter getparm() in matlab window, then send me screenshot

Try this one,

Thank you. I have solved the problem by editing ps_load_initial_gamma.m.
“master_day=str2num(ifgs{1}(nb-21:nb-14));” —> “master_day=str2num(ifgs{1}(nb-27:nb-20));”
I think it is a small bug of StaMPS that the date of the master is extracted and the position of the string is wrong.

I have the same error but in my case, i used SNAP for preprocessing and when i run stamps (1,1) appears the following error. How can i solve it?

Hey, did you find a solution to this? I am getting the same error.

Hi, Karishma.

The consecuense of these error is the selection of the master (or so I think). Sometimes, the master that you choose, has adquisition errors, to much noise or is not compatible to generate ifgs with the others slaves for the high spatial and temporal decorrelation.

I recommed you to change your master one more o less date of your actual master date or try to select the first or the last image in your interval adquisition data.

Into the metodology of snap2stamps, there is a scripts that tries to select your master in order to have the less spatial and temporal decorrelation between this master and the rest of the images. Snap cans also suggest one master that usually works properly.

Another help, is the ASF VERTEX BASE LINE seach type. At this visor, when you are going to select your images, you can see the temporal base linea and the spatial base line of you all interval adquisition in a plot. Its helps to select the best master.

Additionally, at least in SNAP, you can see master alone and check its properties. Then, when you generate the ifgs, make sure that each ifg which this master makes sanse, to save you time for possible errors in stamps
