Hi,

I encountered some difficulties to upload a file using tool interface. This returns the following error, see [1] .Upload a file using "Get data > Upload file" is not a problem. 

Xml tag used for tool definition : <param format="fasta" name="seq" type="file" label="Fasta file"/> 

Python version 2.6.5 (r265:79063)

Do you know how this error can be solved?
Sincerely,

Seb
