Hi--
I am experiencing some inconsistencies when pulling out cluster coordinates. The output of 3dclust give slightly different coordinate values than the ones that I see in the AFNI gui with the report function. I typed on the command line: 3dclust -1Dformat -1thresh 8.23 5 -16 ANOVAfile+tlrc'[3]' > out.1D.
When I click the 3dclust button within the Afni report, the command given is:
3dclust -1Dformat -nosum -1dindex 2 -1tindex 3 -2thresh -8.23 8.23 5 432 ANOVAfile+tlrc. The output of this matches the coordinates in the gui report, but the mean value for many of the clusters is less than 1. Does this seem odd, as p<0.005?
Thank you,
Fatima
