Building GLT file while projecting CRISM cube

[Sehaj]

Hey,

I've been using CAT 7.4 for a long time now. I don't know what has gone wrong. A single CRISM cube is taking approx 10 mins to build GLT file ( see screenshot) while projecting, which earlier used to take seconds.

I have ENVI 5.6 installed on my i9 processor PC with 64 GB RAM. So, I am sure it's not about hardware. Please, anyone, help as I have a plethora of CRISM cubes to process.

Thanks in anticipation!
