Important
As of ATSAS-4.0, every installation of ATSAS requires a personalised license file!
Users of ATSAS that are affiliated with a research or educational institute can request a free academic license over at BIOSAXS GmbH. All that is needed is a working email address at a research or educational institute. If eligible, the license file is sent to the email address provided within ten minutes after the request was submitted. If the mail is not considered eligible, a notice is sent to this address.
Note
Alumni emails provided by some academic institutions may not be eligible for academic licenses. Alumni are asked to contact info@biosaxs.com to clarify the status.
Users not affiliated with a research or educational institute, please contact info@biosaxs.com to request an offer for a commercial license from BIOSAXS GmbH.
Extensively revised and updated manuals are now available at a new location.
That said, not all manuals could be finished in time for the 4.0 release. However, they will be added as soon as possible and further updated over time.
In case a manual you are looking for is either missing, out of date, incomplete or contains an error, please consider submitting an Issue report.
ATSAS-Community includes a Discussion Board.
Post questions and answers, submit Ideas for future ATSAS releases and generally discuss with other users and the developers. If you encountered an issue with any ATSAS application, please consider submitting an Issue report instead of posting in the discussion forum.
Since 2008, the forum over at saxier.org provided a place for this type
of discussions. To preserve the valuable information of this forum, we imported all posts to the
Discussions board where they can be searched as needed. Please note that all saxier.org threads
are locked and labelled
saxier-org
ATSAS-Community also includes an Issue Tracker.
Please submit any Issues you encounter with any of the ATSAS applications and provide the required information to reproduce:
- output of "any-program -v"
- all inputs to the program
- the output of the program
- screenshots to highlight and data as needed to reproduce
In addition, please point out omissions in the manuals or anything that can be improved in future releases. To submit Ideas, please use the Ideas forum.
ATSAS-Community also provides a user-editable Wiki.
Feel free to create pages for any of the ATSAS applications and provide whichever information you consider important to share. For example: Tips&Tricks, relevant publications, use cases, but also limitations of certain applications.
