I created a VS-bird cone catch model based off my non-UV-sensitive camera and using the Peafowl 400-700 visual system. After applying it to the mspec of interest, I’m wondering if there is any way to export only the fourth channel (double cone values) as a TIFF file?
The visual model you have used might not have a specified luminance channel. You can, however, create the luminance channel of your choice by either modifying the spectral sensitivity file (i.e. adding the sensitivity of a specific receptor) and re-training your visual model OR by creating a luminance channel as a combination or copy of existing channels via the steps explained here: http://www.empiricalimaging.com/knowledge-base/adding-a-luminance-channel/. I hope this helps!
