lesion-mapping/spinalcord/3_generate_LFM.py

Line 34 in bec9e39

img.data[img.data>1.0]=0.0

Hello,

I'm trying to replicate this code into bash script using SCT Command-Line Tools.
I'll be very grateful for an explanation what is the purpose of this line.
I was wondering if the partial volume of the transformation can cause some values greater then 1 when dividing the sum of lesions masks by the sum of cord masks , and if so, will multiplying the lesion_mask by the cord_mask for each subject (here) could prevent it?

Thanks a lot
