Hi Ilya, In addition to the ones that you mention, there is also .metadata, .extra_files_path, .name which can be useful. The input wrapper will allow access to any of the attributes associated with the DatasetInstance (see class of this name in lib/galaxy/model/__init__.py), but using these might not be the best idea as they are apt to change. Thanks for using Galaxy, Dan On Oct 17, 2011, at 1:40 PM, Chorny, Ilya wrote:

Is there a list of associated attributes such as $input.ext, $input.dbkey and $input.id?
