Creating a folder robert failed

[haesleinhuepf]

Code:

import biapol_taurus as bt

# This is the mount point at the export node. HPCsupport can tell us this:
source_mount = "/grp/g_biapol/robert"

# This is the project space. HPCsupport told us that when we applied for the project:
target_project = "/projects/p_bioimage/robert"

# We setup a connection:
pft = bt.ProjectFileTransfer(source_mount, target_project)

Error:

I found the source of this error: I create the folder with rsync -a, which tries to set permissions, for which it would need superuser access.

tests within a singularity container confirmed that this error is fixed.
