Dear all,

I've been running into a problem for a number of days now (I've attached a snapshot of the error) trying to run SBAS in StaMPS.

I've ran mt_prep_isce 0.6 4 3 50 200 more than 10 times. So far, I've removed 13 interferograms/folders with error opening reference.slc. For now, I plan to repeat the processing and remove folders with errors (as shown in the image). But this will take long as I'm processing about 1300 interferograms. I'd appreciate a better solution.

I'd be glad if anyone could help with the following information:

1. Am I doing something wrong? If no:

2. Is there a way to identify those folders whose "reference.slc" will fail to open?

3. The first error says "error opening .../reference.slc". Since there's one reference, can I copy reference.slc from the reference folder to these problem interferogram folders? If yes, is this likely to resolve the pscands.1.ij error?

I'd appreciate any assistance.

Cheers,

Caleb.

Updates:

1. Copying reference.slc (item 3 in the original post) did not work.

2. I noticed that reducing the interferometric constraints (temp and perp baselines) reduced the number of problem interferograms

3. I finally got it to work when I reduced the number of interferograms to 400-something.
