Description

preproc-sess runs the following preprocessing steps: motion correction (mc-sess), smoothing (spatialsmooth-sess), and brain-mask creation (mkbrainmask-sess). This will run preprocessing steps: motion correction (MC), slice-timing correction (STC), smoothing, intensity normalization (INorm), and brain mask creation. By default, it will perform MC, smoothing, and masking, but not STC or INorm. All stages producde a new volume that can be used as input to mkanalysis-sess. Note: MC and INorm require matlab but none of the other stages does. By default, motion correction uses the first volume of the first run as the reference for all runs.

Examples

Example 1

To perform MC, smoothing by fwhm of 5mm, and brain mask, run

preproc-sess -sf sessidlist -df sessdirlist -vol-fwhm 5

For MC the input will be f and the output will be fmc For Smoothiing the input will be fmc and the output will be fmcsm5 Use this name (i,e fmcsm5) as the -funcstem argument in mkanalysis-sess.new

Example 2

To perform MC, STC, smoothing by fwhm of 7.1 mm, and brain mask, run

preproc-sess -sf sessidlist -df sessdirlist -vol-fwhm 7.1 -stc

For MC the input will be f and the output will be fmc For STC the input will be fmc and the output will be fmcstc For Smoothiing the input will be fmcstc and the output will be fmcstcsm7.1
