Dear,

I followed all steps in the galaxy tutorial, but I didn't have success.
I'm trying to create a datatype for megabase chromatograms (.esd) very similar to the Ab1 ones.

Here is my configurations.

1 - Creating datatypes in datatypes_conf.xml

<datatype extension="zip" type="galaxy.datatypes.binary:Esd" mimetype="application/zip" display_in_upload="true"/>
<datatype extension="esd" type="galaxy.datatypes.binary:Esd" mimetype="application/octet-stream" display_in_upload="true"/>

2 - Defining types in lib/galaxy/datatypes/binary.py

class Esd( Binary ):
    """Class describing an ab1 binary sequence file"""
    file_ext = "esd"

    def set_peek( self, dataset, is_multi_byte=False ):
        if not dataset.dataset.purged:
            dataset.peek = "Binary chromatograms sequence file"
            dataset.blurb = data.nice_size( dataset.get_size() )
        else:
            dataset.peek = 'file does not exist'
            dataset.blurb = 'file purged from disk'
    def display_peek( self, dataset ):
        try:
            return dataset.peek
        except:
            return "Binary esd sequence file (%s)" % ( data.nice_size( dataset.get_size() ) )

class Zip( Binary ):
    """Class describing a zip archive of binary sequence files"""
    file_ext = "zip"

    def set_peek( self, dataset, is_multi_byte=False ):
        if not dataset.dataset.purged:
            zip_file = zipfile.ZipFile( dataset.file_name, "r" )
            num_files = len( zip_file.namelist() )
            dataset.peek = "Archive of %s binary sequence files" % ( str( num_files ) )
            dataset.blurb = data.nice_size( dataset.get_size() )
        else:
            dataset.peek = 'file does not exist'
            dataset.blurb = 'file purged from disk'
    def display_peek( self, dataset ):
        try:
            return dataset.peek
        except:
            return "Binary sequence file archive (%s)" % ( data.nice_size( dataset.get_size() ) )
    def get_mime( self ):
        """Returns the mime type of the datatype"""
        return 'application/zip'

When I'm going to send the file in zip format (.esd files compressed),it shows me the following error:
"An error occurred running this job: Invalid 'File Format' for archive consisting of binary files - use 'Binseq.zip'"

I tried somethings, but I don't have success.

Thank you,
