[bioontology-support] Problem retrieving classes

[Carlos Oscar Sorzano]

Dear colleagues,

I uploaded yesterday an ontology file for Cryo Electron Microscopy 
(http://bioportal.bioontology.org/ontologies/CRYOEM/?p=classes&conceptid=root). 
The OWL file was generated with Protege and it does not show any obvious 
error in Protege. However, when it is read at BioPortal there is some 
problem because we see the error message "Problem retrieving classes" 
(see previous link). The file is partly parsed because it shows some 
metrics, but we must have something wrong with the file. Could you help 
us with any hint?

Kind regards and thanks, Carlos Oscar
