Hi Guys,
         Did you manage to get multiple datasets working? I can't seem to 
upload multiple files. Only the last file appears in the history. I changed my 
code as mentioned in the thread below in "example_watch_folder.py" to add 
multiple files separated by a new line and increased the sleep time:

for fname in os.listdir(in_folder):
            fullpath = os.path.join(in_folder, fname)
            print ' fullpath is [%s] ' % fullpath
            if os.path.isfile(fullpath):
                data = {}
                data['folder_id'] = library_folder_id
                data['file_type'] = 'auto'
                data['dbkey'] = ''
                data['upload_option'] = 'upload_paths'
                data['filesystem_paths'] = 
"/home/galaxy/galaxy-drop/input/141_S_0851_MRI_T1_Screening.nii.gz\n 
/home/galaxy/galaxy-drop/input/141_S_0851_MRI_T2_Screening.nii.gz"
                print ' data is [%s] ' % str(data['filesystem_paths'])
                data['create_type'] = 'file'
                libset = submit(api_key, api_url + "libraries/%s/contents" % 
library_id, data, return_formatted = False)
                #TODO Handle this better, but the datatype isn't always
                # set for the followup workflow execution without this
                # pause.
                time.sleep(65)

However, I get the following crash:

It says there is no such file, but this file has already been copied from the 
input to the output directory. Any help much appreciated

Hi Dannon,

I've written some code to (i) query a dataset to ensure that it's been
uploaded after a submit and (ii) to ensure a resulting dataset has been
written to the file.

*#Block until all datasets have been uploaded*
libset = submit(api_key, api_url + "libraries/%s/contents" % library_id,
data, return_formatted = False)
for ds in libset:
    while True:
        uploaded_file = display(api_key, api_url +
'libraries/%s/contents/%s' %(library_id, ds['id']), return_formatted=False)
        if uploaded_file['misc_info'] == None:
            time.sleep(1)
        else:
            break

*#Block until all result datasets have been saved to the filesystem*
result_ds_url = api_url + 'histories/' + history_id + '/contents/' +
dsh['id'];
while True:
    result_ds = display(api_key, result_ds_url, return_formatted=False)
        if result_ds["state"] == 'ok':
            break
        else:
            time.sleep(1)
