Hi

I am going to convert my cobra model to sbml, i use this command:

writecbmodel(model,'SBML')

then it opens a box to save the file, when i write a filename with out .xml extension in the file nam box it gives me the error: "writecbmodel at 50" fileName=[filePath tokens{1}{1}];

When I write a filename with the xml extension it gives me two errors:

1. ConvertCobraToSBML at 105; and
2. WriteCbModel at 255

I reviewed all the given errors, but I couldn't fix them

Can anyone help me?
