Subject: [Ifit-users] iFit 1.7 released
Message-ID: <9945dd4de5fab1a06a964b82fe16d7f6@ill.fr>

 Dear iFit users,

I'm happy to release the version 1.7 of iFit, dated Oct 14th 2015.

It provides the following changes wrt the previous version 1.6:

OPUS FT-IR, LLB TAS, LabView LVM and TDMS file format import. Fixed
curvature in ResLibCal/Rescal5/Popovici method. Added predefined TAS
configurations in ResLibCal and cross-checked computation methods. Fix
TAS angles in 3D view. Initial support for nD Gaussians and 4D TAS
convolution. Added Gaussian smoothing. Compatibility with Matlab new
graphic objects (R2014b). Better handling of arguments to standalone
iFit. Added fill method to remove NaN's in iData objects. iFunc 4D
S(q,w) models from either analytical or ab-initio methods.

The 4D S(q,w) models using external software (ASE and Quantum Espresso)
do not work properly from the standalone version. If you need these,
consider buying a Matlab license.

The ResLibCal application for neutron TAS has been upgraded, and can be
used for 4D convolution of models (iFunc). Launch ResLibCal and access
its Help menu for more information about capabilities. 
It is distributed as source code (req. Matlab license), and as
standalone for Linux 64 bits, Windows 64bits and Mac OS 64 bits (which
all do not require any Matlab license).

Documentation and Installation instructions at
<http://ifit.mccode.org/>.

If you find bugs, please submit tickets at
<https://github.com/McStasMcXtrace/iFit/issues> or send me an email.

The source code is fully available at
<https://github.com/McStasMcXtrace/iFit/>. You can contribute by
forking, then modify, and actually send a pull request. If this seems
completely non-sense to you, just send me suggestions or any
modification to the code via email. I'll be happy to have your
contributions for the next releases.

If you use this software and produce valuable results, please cite:

Hi Victor,

This issue is related to libraries shipped by MATLAB being older than
that of the system.
In your case this relates to LIBGCC_S. Other libraries may also be
concerned, e.g. LIBGFORTRAN.
I suggest an iterative solution.

REMOVE THE MATLAB LIBRARY
% sudo mv
/opt/MATLAB/MATLAB_Compiler_Runtime/v713/sys/os/glnxa64/libgcc_s.so.1
/opt/MATLAB/MATLAB_Compiler_Runtime/v713/sys/os/glnxa64/libgcc_s.so.1.org

then try again in case MATLAB would seek for the library from the
system.

IF THIS DOES NOT WORK, COPY THE SYSTEM LIBRARY IN PLACE OF THE MATLAB
ONE
% locate libgcc_s
/lib/x86_64-linux-gnu/libgcc_s.so.1
/usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s.so
% sudo cp /lib/x86_64-linux-gnu/libgcc_s.so.1
/opt/MATLAB/MATLAB_Compiler_Runtime/v713/sys/os/glnxa64/libgcc_s.so.1

Tell me if this works.
Emmanuel.
