Re: [scipion-users] multiuser mode

[Jose M. de la R. T. <del...@gm...>]

Hi David,

I think that the SCIPION_TESTS is configurable, but we don't use that
option very often. Could you try to provide the full absolute path?

Anyway, I will recommend to download the test data in advance and allow
users read-only access. Some of the datasets for the tests
contains big files (needed for real EM tests) and you can end up with many
copies of this test data per user.

Where is the --paths options that you are asking about?
