Feedback and Notes
Rick has a page of IVAS screencasts. NUCAPT users are invited to provide feedback on IVAS.
IVAS ships with software initially written by Mike Miller, including the envelope method that is partly based on Jon Hyde's maximum separation method. The version included with IVAS 3.0 and below (envelope-2.1) have memory limitations and occasionally have seek errors. Mike and Imago graciously allowed Richard Karnesky to modify the source code to work with larger datasets. This version (envelope-2.3 and above) also implements a parser for Imago range files (in addition to the parser for ORNL files that Mike wrote). NUCAPT can make binaries of this program available only to customers that already have a copy of IVAS. The information for the most distributed windows binaries of these different versions are listed below:
Checksums may be checked with wxChecksums:
- Download any linked checksum, above
- Open it with wxChecksums
- If you are using the same version of IVAS as was used to generate the fies, you will be told whether your checksums are O.K.
- If you are using a different version of IVAS, click & drag the envelope.exe to the window & manually compare the two checksums.
