Additional Info

On tintin you can use:

export ATTRACTDIR=/trinity/login/arha/tools/attract/bin
export ATTRACTTOOLS=/trinity/login/arha/tools/attract/tools
export LD_LIBRARY_PATH=$ATTRACTDIR:$LD_LIBRARY_PATH
export LIBRARY=/trinity/login/arha/tools/nalib
export RANDSEARCH=/trinity/login/arha/data/ssRNA/randsearch

instead of installing ATTRACT from scratch

What about creating a Docker/Singularity container instead with everything inside ?
I am thinking here of a solution for the web app.

Not really an option for this case, the third-party software has a hard dependency on py2 while this project is py3. Making a container in which both can co-exist will a bit complex. Makes more sense to containerize the older code and build a wrapper for it.

For attract specifically the maintainer has published an image @ rbps/attract (mobyle2.rpbs.univ-paris-diderot.fr something repository) which can be seamlessly integrated into the web interface as well - it's all the same technology :)

@rvhonorato, can you add here the docker-related script(s) you made, please?
And that 1-line call that allows to run /path/attract/tools/reduce.py. Thank you!
