Michael-S-Phillips / SCAT

Spectral Cube Analysis Tool. Simple python GUI for displaying and investigating spectral cubes. Meant to work with two displays: the spectral cube on the left and a parameter RGB on the right.

At this point, the output directory is missing the file with previously computed parameters. Is there a way to skip parameters that go in error and save the ones computed?

Hello Alessandro,

The issue has to do with how SCAT is set up to run, which involves having two images loaded (a hyperspectral cube in the left frame, and a parameter or pca cube in the right frame). It looks like you were calculating a parameter cube to place in the right frame. When you get to this window: @. You’ll press Initiate which brings up the parameters which will be calculated in this window: @. Here, you can remove the RPEAK1 and BDI100VIS parameters to avoid the issues with calculating these parameters which can sometimes fail for several reasons.

I’ll make updates to the code to do as you suggested and be robust against failures in parameter calculations, saving the successful parameters and skipping the ones that fail.

Best, Michael
