sliceacq is a command-line program to do slice timing correction. It sinc interpolates each time series to create a new one aligned at time 0 (the time of the first slice in the volume). Here's the help:

sliceacq - Acquisition correction routine for VoxBo.

usage: sliceacq -h -r -i[4D data file name] -o[output file name] 
                -s[slice time] -t[time of 1st slice] -c[TR time]
                -p[configuration file] -v
flags:
-h                        Print usage information. Optional.
-r                        When used, the default behavior of not performing
                          correction on a corrected file is overridden.
                          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.
-s <slice time in ms>     Specify the slice time in milliseconds.
                          Values <= 0 are treated as if the slice time was not
                          specified. Optional.
-t <time of 1st slice>    Time of first slice in milliseconds. Must be a non-
                          negative float. Optional.
                          NOTE: If -s is used but not -t, then time of first
                          slice is assumed to be 0. Conversely, if -t is used
                          but not -s then slice time is set to
                          (tr - time of 1st slice)/dimZ.
-c <TR time in ms>        Specify the TR time as an integer number of
                          milliseconds. This overrides the TR value from the
                          header. Optional.
                          NOTE: Non-positive values are ignored.
-p                        Configuration file path. Default is
                          /usr/local/VoxBo/etc/sliceacq.cfg
-v                        Global VoxBo version number. Optional.
-n                        Assume interleaved slice order (default is ascending).
