Hi again, Emboss_datatypes is installad via tool shed. The 'View datatypes registry' in the Adminstration page, shows all registered data types, including the emboss ones, like e.g. genbank. However, the 'Upload File' tool does not show genbank in the 'File Format' dropdown. How can one configure the upload1 tool so that all registered formats are listed ? I don't understand the from_parameter hocus-pocus in this line (upload.xml): <options from_parameter="tool.app.datatypes_registry.upload_file_formats" transform_lines="[ "%s%s%s" % ( line, self.separator, line ) for line in obj ]"> The workaround which is used up to now is upload genbank sequences as txt format and change the format later via the history. But that is a 2-step operation, guess there should be a way taking only 1 step ?
