===== TUI information =====

==== Python dependencies for linux users ====

TUI has strict python dependencies.  Many linux users have problems 
displaying guider or slitviewer images because they have the wrong 
version of one or more packages.  Even if TUI is built correctly, 
running it from the wrong directory might result in a different 
package being loaded.  Since individual linux and python setups can 
vary widely, the same solution might not work for everyone.  But 
here are some solutions that have worked for some people.

=== Pre-built TUI 2.6.0 ===

Download a copy of TUI pre-built for linux as of December 2017 at

http://www.apo.nmsu.edu/35m_operations/TUI-images/files/tui-centOS.tar.xz

Future TUI versions will be linked from the TUI-images web page so
be sure to check there also.

=== Install from the ground up ===


  - install miniconda2 using the usual installer
  - in miniconda2/bin do ./conda install python=2.7.12 to revert to python 2.7.12
  - create a file "pinned" in miniconda2/conda-meta with the line python ==2.7.12
  - in miniconda2/bin do "./conda install numpy=1.8.2" to install numpy 1.8.2
  - add line "numpy ==1.8.2" to "pinned"
  - in miniconda2/bin do "./conda install matplotlib"
  - in miniconda2/bin do "./conda install Pillow"
  - in miniconda2/bin do "./conda install astropy"
  - in miniconda2/bin do "./pip install pygame"
  - in miniconda2/bin do "./pip install RO==3.6.9”
