The technical report (or user's guide) mentions software features or techniques that do not seem to be included in the software released on this site. Why is that and where can I get those?
In the interest of offering a cleaner, simpler software package and to resolve some licensing issues for this initial public release, some functionality was removed from the software delivered to NIJ with the technical report. We do plan to continue development (as time permits) on the current codebase, and the extra features and functionality formerly available will likely be the first to be added. 
Feature X doesn't work--where can I get help?
Post a message to the forums, and the project administrators will do their best to answer your question promptly. Or send a message directly to a developer by clicking on his/her Sourceforge username (visible on the main project page sourceforge.net/projects/level3tk). 
Why do I get the following message:
Mindtct.exe cannot be found; exiting.
...when I know I have
mindtct.exe
or I am using Linux and my
mindtct
does not have an
exe
extension?
Try setting the path to the 
mindtct
executable by using a configuration file. See the MINDTCT Path section of the [L3TK_Feature_Extractor_Configuration] article. The error message is (unfortunately) not platform-independent: it calls the
mindtct
executable
Mindtct.exe
whether it was looking for the file at the pathname with or without the
.exe
extension.
