NIS (NeuroImaging Software) package version 3.3    June 30, 2000


Changes from NIS 3.2

- Added nisthresh, nismask, nishemo, nisfilter, overlap, and
  plist_split programs and rename script
- Modified various script defaults to make installation easier
- Merged nistimemean and timevectors into niscorrect; added blocking
  factor to detrend and outlier corrections
- Modified baseline correction in niscorrect to account for pixels that
  become negative and are set to zero in computing baseline adjustment
- Implemented thresholding in niscorrect
- Added new routines for simpler analyze read/writes; uncompression is
  now done in-place instead of copying images to a temporary directory
- Fixed problem with nisexpand where expanding a single slice resulted
  in a blank slice
- Modified nisexpand and nisoverlay to print verbose output to standard
  output instead of standard error
- Fixed problem with nisroi where pixel values were being evaluated
  against the significance value threshold inconsistently (greater than
  or equal to the threshold at first, and strictly greater than the
  threshold afterwards).  Now nisroi always looks for pixel values to
  be greater than or equal to the significance threshold, which is also
  consistent with the way the contiguity threshold is evaluated.
- Modified nisoverlay to also overlay pixels that are equal to the
  significance threshold, to be consistent with nisroi.
