I was wondering if it's possible to replace or turn off your denoising algorithm `mri_nlfilter`. We'd like to try different denoising filters and compare how they influence segmentation performance. Right now we're applying filter before running recon-all, but I fear that applying your filter on already filtered image might degrade our analysis.

I couldn't find any mention of mri_nlfilter besides this one on mailing list https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2011-October/020762.html. I hope I didn't miss something anything.

Thanks!
