Issue Tracker Database is Down & SBML model not read anymore in 4.37 (Build 264)

[Matthias König]

Hi all,

I just tried to read the attached SBML model with the new COPASI release.

This fails with

Error while loading file /home/mkoenig/git/pkdb_models/pkdb_models/models/pravastatin/models/results/pravastatin_liver_cholesterol.xml!

>EXCEPTION 2022-10-20T15:38:12<

SBML (55): Could not find unit definition for unit with id "m2" used in "units" attribute of compartment with id "Vbaso".

Resulting in an empty model without objects.

- The model is valid SBML

- The model could be read with the previous COPASI version

There were some major bugs introduced with units support in the lastest COPASI version.

Model is attached.

I tried to report the bug, but the tracker database is down at

http://tracker.copasi.org/

Software error: Can't connect to the database. Error: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) Is your database installed and up and running? Do you have the correct username and password selected in localconfig?

Hello Mathias,

Thanks for reporting both issues. The database has been restarted and
the tracker is running again. I will look into the issue.

Thanks,
Stefan

Hello Mathias,

The error message is misleading and should only be a warning. COPASI
stumbles over the use of an area unit m^2 for a 3 dimensional
compartment basolateral membrane (VBaso). Correct the dimension of your
compartment and you should be fine.

Thanks,
Stefan

Thanks Stefan. This fixed the issue with model loading and improved the model ;)

The old COPASI Version 4.36 had no issue with the spatialDimensions and read the model without issue. I always thought the spatialDimensions are mainly for annotation, but do not have meaning for the actual math/model. So it is strange that this results in the model not being loaded in the new version 4.37.

Best Matthias

Hello Mathias,

The check for appropriate units has been improved however an incorrect
message was generated. This will be fixed in the next release.

Thanks,
Stefan
