AfniSqwave
AfniSqwave is a wrapper for the AFNI (RW Cox, NIH) sqwave application.
sqwave -- It allows for the creation of time series file that consists of "on" periods (10's), "off" periods (0's), and "unused" periods (99999's).
AFNI sqwave was written by Medical College of Wisconsin.

- ignoring first
This specifies the number points of the beginning of "on" period to ignore (number of 99999's in the "on" period).
- Off period:
- length

- ignoring first
This specifies the number points of the beginning of "off" period to ignore (number of 99999's in the "off" period).
