Problem with loading .geof file from MAP repository

[NataCalc]

Hello Ju,

I am experiencing problem with loading .geof files from MAP repository using load_geometric_field and load_gf_shelve functions. Attempt is to load filename=femur/baseline-214/fieldwork_mesh/femur_right_mean_cortex_outer_rigid_214.geof . As load_geometric_field function contains if open(filename) else shelve.open(filename) I am testing .geof file launching python via terminal:
