Loading non-height Gamma files (watermask, incidence angle, etc...) into mintpy

[ZachHoppinen]

DISREGARD - Turns out I just needed to add .hgt_sim to the end of the inc, watermask, shadow mask files, update my .cfg file and re-run to get at least the incidence angle file to be loaded.

Hello,

I am attempting to run a stack of GAMMA processed unwrapped phase files through mintpy with watermasking. I can get the processing chain to work when I only provide a radar coordinate height file and lookup table.

########## 1. load_data
BYTE_ORDER=big-edian
##---------interferogram stack:
mintpy.load.unwFile         = /data/nga/2024/Oliktok/SLA22/mintpy/interferograms/*.unw  
mintpy.load.corFile         = /data/nga/2024/Oliktok/SLA22/mintpy/interferograms/*.cor 
##---------geometry:
mintpy.load.demFile         = /data/nga/2024/Oliktok/SLA22/mintpy/geometry/20240507.Oliktok.hgt_sim 
mintpy.load.lookupYFile     = /data/nga/2024/Oliktok/SLA22/mintpy/geometry/Oliktok.to_rdc
mintpy.load.lookupXFile     = /data/nga/2024/Oliktok/SLA22/mintpy/geometry/Oliktok.to_rdc

However when I add incidence angle and water masking files that have been geocoded to radar coordinates i.e. adding:

mintpy.load.incAngleFile    = /data/nga/2024/Oliktok/SLA22/mintpy/geometry/20240507.inc
mintpy.load.shadowMaskFile  = /data/nga/2024/Oliktok/SLA22/mintpy/geometry/20240507.ls_map_rdc
mintpy.load.waterMaskFile   = /data/nga/2024/Oliktok/SLA22/mintpy/geometry/20240507.wm

I get the error: ValueError: unsupported input file extension: .inc coming from cli gamma_prep.

The only acceptable extensions seem to be '[.unw', '.cor', '.int', '.dem', '.hgt_sim', 'to_rdc', '2_rdc', '2rdc']. None of which seem to match incidence angle or water masks.

Any advice on what to do to add incidence angle files, watermask, etc to the mintpy pipeline when using GAMMA products?

Thanks!
