Preprocessing Sentinel-1

I am currently working in ENVI, because I want to run the SAR Flood mapping tool in SARScape Analytics Engine. I have no SARScape toolbox, however (it was not bought for this license) and so I’m doing preprocessing in SNAP.

I just realized that after doing any correction (AOB, S1 TOPS etc) the result is polarized bands and the file disappears, which I need to run the flood mapping tool.

Is the file conserved during preprocessing in ENVI? Or is there no preprocessing allowed before running any tool that needs a file?

SNAP can only read the manifest file, but not export it.
