+# Topaz
+
+[Topaz](https://github.com/tbepler/topaz) is a conda-based cryoEM particle
+picker. It is used primarily through cryosparc, but also provides python
+notebooks.
+
+See https://intranet.psi.ch/en/bio/computing-cryosparc
+
+## INSTALLATION
+
+IMPORTANT! DON'T INSTALL WITH AURISTOR. Use an OpenAFS system (e.g. pmod6)
+
+    export TMPDIR=/opt/tmp/$USER
+    export XDG_CACHE_HOME=/opt/tmp/$USER/.cache
+    CONDA_COPY_ALWAYS=1 conda env create --file topaz.yml
+    conda activate topaz-0.2.5
+
+The alternate TMPDIR is required on pmod6 because /tmp is too small for pip to expand all wheel files.
