Neuroimaging analysis software

Three directories are included: c, idl and FIDL.
Most of the computing is done in C/C++ whose code resides in the "c" directory.
The user interface is written in the IDL scripting language whose code resides in the "idl" directory.
The FIDL directory includes
      "build": linux built libraries and binaries
      "fidl": CMakeLists.txt for building the libraries and binaries. You will need to edit it.
      "cifti/build": place holder for CiftiLib (https://github.com/Washington-University/CiftiLib) - prebuilt one included
      "gsl": place holder for the gsl library (https://www.gnu.org/software/gsl) also called by fidl
In addition fidl calls RSCRIPT with scripts written on the fly by the binaries:
      fidl_anova6.cxx calls the R lmerTest which calls the lme4 library.
      fidl_pcat.c calls the RCUR library

It's greatest strengths are its general linear models, average statistics, repeated measures ANOVAs and linear mixed effects.
Now accepts Freesurfer style *LUT.txt files to identify regions in niftis in addition to 4dfps with regions taking integer values from 2 upward.
