vbthresh

From VoxBoWiki

vbthresh thresholds 4D volumes. Any voxel which is below threshold for any time point in the time series is set to zero at all time points. So if you have one blank volume in your time series, vbthresh will zero out all your data. Here's the help text:

vbthresh - threshold routine for VoxBo.

usage: vbthresh -h -i[4D data file name] -o[output file name]
                -c[threshold cut off value] -b[bin size] -v
flags:
-h                    Print usage information. Optional.
-i <4D data file>     Specify the input 4D data file. Required.
-o <output file>      Specify the output file name. Optional.
                      Default output file name is the input 4D data file name.
-c <threshold value>  Positive integer threshold cut off value. Optional.
                      Default value is 600.
-b <bin size>         Positive integer specifying the bin size if histogram
                      thresh holding is to be used. NOTE: -b takes precedence
                      over -c unless the bin size is 0. Optional.
-v                    Print global VoxBo version. Optional.
