Hi,
I'm hoping that the list can help me out.
I'm trying to write some tools to capture elements to ease migration from a
course development
server to a training server. I'm using the Bioblend API which I am a newbie at
using.
In the code for extracting the data files from shared data libraries all is
well except for 'Tabular' data
(e.g. fasta and txt are OK). The error seems to be at the stage where the
program calls the Bioblend
.datasets.download_dataset() function.
NB The tabular files in question can be downloaded fine from the server on the
appropriate Galaxy page.
(My code is at the end of this message - Please forgive the quality of my
Python code).
If a tabular data file is present then I get the following output & errors from
my program:-
Root path: /usr/users/fr009/fernande/gal_exports/data
Library: Intro Galaxy Training
No. of items in library 11
>> /usr/users/fr009/fernande/gal_exports/data/Intro Galaxy

>> /usr/users/fr009/fernande/gal_exports/data/Intro Galaxy

Also note that :

g_vers['version_major']
Outputs]:

Any help/elucidation gratefully received (I'm on a learning curve here) :-)
Thanks in anticipation.
