Hi FSL group,
I have run the steps in order to complete a volume analysis using FIRST. My last step was to use fslstats to get the volume (ex. fslstats lcaudate -V). However, the volume is in subject-specific T1 space. How do I get this value to be in standard space? I've read the archives and it seems that I should use the avscale command. However, I am a bit confused on the exact commands and how to get the end result that I can put into a stats program like SPSS.
From my fslstats command, I get the volume from every subject (by using the 2nd number provided in the fslstats -V command) in T1 space. What are the exact commands to use avscale? I'm still unsure even after reading the usage...
For every subject I have a file called T1_to_std_sub.mat, is this the file I should be using?
ex. avscale T1_to_std_sub.mat
If this is the correct usage, what is the number I should use to multiple the volume in T1 space to get it to standard space? Is it the number found in Average Scaling (ex. Average scaling = 1.11215)?
Sorry for all the questions!!
Best,
Dana
