Dear all,
I’m using the ISCE/StaMPS to do a time-series analysis, and all the steps work well on both software without any error. It must be said that my study area has a high variable topography and applied PSInSAR to do so. You can see the results in the following:

ps_info after finishing all steps of PS:

ps_plot ‘w’:

ps_plot 'w'.png

ps_plot ‘u’: Could you please let me know if the unwrapped ifgs have an abnormal color/presentation?

ps_plot 'U'.png

After running the Velocity command [ ps_plot(‘v-d’,1,0,0,[1:3,7:8],‘ts’) ], I got the below error:

I changed the ref_radius and 67 ref PS were selected but still got the same error!

Any assistance would be greatly appreciated...

Dear all,
After a long search and studying the previous discussions (such as https://groups.google.com/g/mainsar/c/sd9oVlTgB9U/m/7fwWE_68BAAJ),
I found that may change the value of "merge_resample_size" and "unwrap_grid_size" parameters to higher than 50 (100 0r 200), of course for the
small area (landslide caused deformations) with high topography variations could solve the issue. Done and got better results without mentioned errors.

Cheers
Peyman
