Glad to see that snap2stamps works fine for you as well!
Regarding the mt_prep_gamma_snap run you made, could you tell me which values were reported as amplitude average per scene? if it was written in the script an s instead of f for the format type, the script will return values over 0.xxxxx instead of being a lot higher, and then you may get errors later inside StaMPS processing.
Regarding your question, in both cases you should let on the search folder only the data that you want to process or export.
- the splitting starts with reading data within the slaves folder, but later steps read all the other folders
- the stamps export reads the folders ifg and coreg
The current best option is to moved the already processed data. But with this indeed grows the need of the overwrite option (true or false) for the processing. I will take care of it.
Thanks for the comments.
