Hi all,
I am starting to use QAtools in Freesurfer. The scripts are working well, but I have two problems:
1. the interpretation of output is the first. Are there ranges of normality for SNR and intensity? Could you please give me some reference or link about how to interpret these data? Or do I only need to look at outliers (or something similar)? My values are in the range between 19 and 25 (and the subject with 19 have problems at visual inspection). The script also outputs 'no outlier' in all my subjects. Which type of outliers is it referring to?
2. I have also problems in getting snapshots, but I think this is due to my poor experience with setting paths of ImageMagick. I am using a MAC OSX 10.6.8 and I used (tcsh) setenv MAGICK_HOME /Applications/ImageMagick-6.9.2/bin but probably this is not enough (any suggestion is greatly apreciated).
Thank you for any help you can give me
Best wishes
Angela
