Hi,
I'm trying to perform statistical analysis of FA images using randomise. I have four different subjects with FA images that were created using this website:
http://wikis.la.utexas.edu/imagelab/book/how-prepare-your-dti-images-fractional-anisotropy-fa-analysis Then I used
http://wikis.la.utexas.edu/imagelab/book/statistical-analysis-fa-values to do the analysis. It says that you need the FA skeletonised image in the stats directory, but when I'm comparing 4 subjects how should I rename the FA images so that I can compare
all of them. I have to rename them or else they would overwrite each other because they have the same name under each of the subjects stats directory. When I tried this command:
randomise -i all_FA_skeletonised -o tbss -m mean_FA_skeleton_mask -d design.mat -t design.con -n 500 --T2 -V
an error occurred saying FA image volume couldn't be read when I had a number or letter in front of the "all_FA_skeletonised" and "mean_FA_skeleton_mask" images in order to distinguish between the subjects. I also tried putting a * in the command but it had
the same error. It could only read the image when it was the original name of the image with no letter or number in front.
How should I save the images so that this problem doesn't occur?
