You can see a partial list in the Readme file in <br class=""> <a href="https://sciserver.mpe.mpg.de/dashboard/files/datavolumes/4" class="">https://sciserver.mpe.mpg.de/dashboard/files/datavolumes/4</a><br class=""> and can see all installed python modules and their version with "conda list”<br class="">- In the Xray images the HE software collections have been updated to HEASoft 6.31.1, CIAO 4.15, eSASS 20211214.0.5.<br class="">- In addition the CIAO installation has been changed to be part of a conda environment instead of a separate software installation.<br class=""> The Xray and eSASS images have additional buttons buttons and command line instructions to run with the CIAO kernel. <br class=""> Please note that this environment does not come with all the same modules installed as the base environment.<br class="">- Lastly there is now a a easier way to modify your environment and have it stick between containers: In a interactive shell the bash setup will attempt to source the file <br class=""> Storage/[user]/persistent/bashrc if it exists. So you can add your preferred shell configuration to that file. <br class=""> I hope you will find everything working as intended. If you encounter any issues, please let me know - It is at times challenging to get all the various software installations to play nicely with each other.<br class=""><br class="">Kind regards<br class="">Jonas<br class=""><br class="">—<br class="">Jonas Haase<br class="">Max Planck Institute for Extraterrestrial Physics (MPE)<br class="">Giessenbachstr. 1, 85748 Garching, Germany<br class="">X5 1.3.08<br class="">+49 89 30000 3706<br class=""><br class="">-- <br class="">Sciserver-users mailing list<br class=""><a href="mailto:Sciserver-users@lists.mpe.mpg.de" class="">Sciserver-users@lists.mpe.mpg.de</a><br class="">https://lists.mpe.mpg.de/cgi-bin/mailman/listinfo/sciserver-users<br class=""></blockquote><br class=""></div></div></blockquote></div><br class=""><div class="">
