Usage of Topaz in cryosparc v2.15.0


Should I install Topaz seperately or it’s included in cryosparc v2.15.0?
I tried to run Topaz in cryosparc with default to “Path to Topaz executable” and found some below error.

[CPU: 163.1 MB] Traceback (most recent call last):

assert topaz_exec_path is not None, “Must provide path to Topaz executable.”
AssertionError: Must provide path to Topaz executable.


Hi Jianhao,

Topaz must be installed separately from Cryosparc. Then the executable must be pointed to in the Topaz jobs.

Installation and usage instructions are here:

Let us know if you have any issues with Topaz.
