Dear experts: I am on my way to interpret the results of FSL VBM and I am doing my cluster part. I write cluster -i GM_mod_merg_s2_tstat1.nii.gz -t 2.5 -o cluster_index_s2_1 --osize=cluster_size_s2_1 > cluster_info_s2_1.txt But I am not sure of the results because all the coordinates are positive and of course the atlasquery would give me disparate results the vast majority is unknown and or pretty much the same areas in the brain. I copied from cluster -i myinputimage -t 2.5 -o cluster_index --osize=cluster_size > cluster_info.txt I do not know if myinputimage is any *tstat*.nii.gz file. Thanks for the help! Sincerely, Andrade. PD I forgot to mention in the processing stream I did fslmaths GM_mod_merg -s 3.5 GM_mod_merg_s3.5 after this randomise -i GM_mod_merg_s3 -m GM_mask -o fslvbm -d design.mat -t design.con -T -n 5000 I do not know if that is relevant and in that case how to fix it probably deleting output files from randomise and re-run from fslvbm_3_proc ######################################################################## To unsubscribe from the FSL list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=FSL&A=1
