I am doing FIRST segmentations by doing the individual steps rather than using first_all as a colleague found that this works best for us. The boundary correction step they were using is:
first_utils --singleBoundaryCorr -i (input file) -r (reference file) -p 3 -o (output file)
However, I cannot see this command on the FSL website. Is this command still valid with version 4.1.5? The boundary correction command on the website is:
first_boundary_corr -s segmented_image -i intensity_image -b method -o output_name
I would like to know which I should be using.
