FIT

FIT is a program to display data files and to fit standard or user-defined
functions. It can read many types of data files, mainly neutron scattering
data. It is extensible for other datafiles types, please ask the author listed
below how to implement new data files structures. It may also be used as a
library for automatic fit programs or simply to convert data files.
The original FIT program was based on an old version of the CERN Minuit
library. Since 1990, it was extended and improved continuosly.
There is a built-in help facility, where you can find most of the features
FIT offers (HELP command).

Installations instructions
--------------------------

Various flavors of Unix (Tru64, Linux, Mac OS X):

  for installing fit from source you need the pgplot and readline libraries,
  if you like nexus support you need also the nexus API, hdf and hdf5
  and the compilers gcc and g77 (other fortran compilers may need source
  adjustments)

  Unpack the sources, creating the directory tree ./fitsrc/...
  and go to the source directory:

  > gunzip fit.tar.gz
  > tar -xvf fit.tar
  > rm fit.tar                (assuming you dont want fit.tar as a backup)
  > cd fitsrc

  Here you can find several system specific makefiles:

  > ls makefile_*
  makefile_alpha  makefile_alpha_f  makefile_linux  makefile_macosx

  These files are for Tru64 Unix (normal and fast version), RedHat Linux
  and Mac OS X.

  Edit one of these file to define where the needed libraries are.

  Define an environment variable for your version, for example

  > setenv FIT_VERSION linux

  You may define this also at login.

  Then simply enter

  > make all

  to make all of fit.

  On Linux and Mac OSX systems you should use DEB=D for the debugger
  friendly, non-optimizing version. The optimized version is buggy.
  On Tru64 Unix the optimized version is substantially faster.

VMS:

  To build FIT and some related programs execute the CONFIG.COM command
  file. It will give you further instructions.


  Example:

  Let us assume that the sources are in directory [USER.FIT.SRC...]
  and that the prompt is $

  $ @[USER.FIT.SRC]CONFIG
  DRA0:[USER.FIT.EXE] created
  DRA0:[USER.FIT.DEB] created
  DRA0:[USER.FIT.EXE]MAKE.CFG; created
  modify this file to define where to find the libraries
  then use MAKE to make all targets in directory DRA0:[USER.FIT.EXE]
  or MAKE -D to make a debugger friendly version in directory
  DRA0:[USER.FIT.DEB].
  To get some help on the MAKE command type MAKE ?

  $ MAKE
