External Email - Use Caution

Dear experts:

I performed cluster-wise correction for along-tract measures using mri_glmfit-sim as documented here ( https://secure-web.cisco.com/1YmsMw8LA5K4vjKmpPSbf5iYXXniVrshoE73mbH13u44Iuo... Now, I would like to use drmi_trk2trk to embed the corrected statistical results into the template .trk file, as shown by the command below.

dmri_trk2trk --in $FREESURFER_HOME/trctrain/hcp/syn/lh.uf.display.trk \ --out trc/stats/lh.uf.overlay.trk \ --over trc/stats/lh.uf.RD_Avg.glmdir/contrast1/sig.mgh \ trc/stats/lh.uf.RD_Avg.glmdir/contrast1/z.mgh

Which of the contrast files should I overlay to show the corrected results? Are the "sig.mgh" and "z.mgh" files corrected for multiple comparisons after running mri_glmfit-sim? Running mri_glmfit-sim with positive contrast for example generated the following output files, but which of them correspond to the "sig.mgh" and "z.mgh" files? I would greatly appreciate if anyone who knows the procedure teaches me to do this.

perm.th13.pos.max.cwpval.txt perm.th13.pos.pdf.dat perm.th13.pos.sig.cluster.mgh perm.th13.pos.sig.cluster.summary perm.th13.pos.sig.masked.mgh perm.th13.pos.sig.ocn.lut perm.th13.pos.sig.ocn.mgh perm.th13.pos.sig.voxel.max.dat perm.th13.pos.sig.voxel.mgh perm.th13.pos.y.ocn.dat

Sincerely, Takashi Tarumi
