Hello,
I have been using the pipeline05 to process old 'not-so-good' images. I have noticed a strange thing that happens on all images with the default parameters : the brain mask looks like it has been "closed" (morphologically). That is of course propagated to further steps, and even the grey-white interface looks closed or dilated. The bias corection step looks alright, may be the histo analysis is wrong...
I include the snapshots of the different steps of segmentation below. Does it ring a bell, anything already encountered ?
Thanks in advance.
Olivier
