How to quantify results for FSL FIRST, after stats have been generated.
Clusters
For a stats file "L_Hipp_vertexMNI_rand_tfce_p_tstat1.nii.gz" for example, you can get information based on standard FSL reporting (this page has several examples).
The following two commands are probably the most useful:
Defining clusters (see FSL guide)
[datauser@localhost temp]$ cluster -i L_Hipp_vertexMNI_rand_tstat1.nii.gz -t 2 -o cluster_index --osize=cluster_size > cluster_info.txt
P values and t statistics
[datauser@localhost temp]$ cluster -i L_Hipp_vertexMNI_rand_tfce_p_tstat1.nii.gz t 2 -c L_Hipp_vertexMNI_rand_tstat1.nii.gz scalarname="1-p" > cluster_p1.txt
- leave off "> cluster...txt" to display on screen
