The UM ancillary generation process uses ANTS (behind MOSRS firewall) . ANTS is available on analysis3, but it is an older version (0.19) which doesn’t work with some of the Regional Ancillary Suite ANTS (1.0) or the JULES offline ancillary suite ANTS (1.1). I can run existing scripts on gadi using …

The ancillary suites normally install and use their own copy of ants rather than using the one in the conda environment. The conda environment only supplies dependencies. If the dependencies are compatible (they probably are) you should be able to swap out the module load ants/1.1.0 in the ancillar…

Thanks Scott, although we want to use ants interactively (for development) rather than through the ancillary suite. Also I haven’t been able to get RAS ANTS code (based on ANTS 1.0) running with analysis3 ANTS (0.19). Confusingly, the RAS uses module load ants/0.18 even though it’s sourcing a branc…

Creating your own environment is an option, if inodes are an issue you can put the environment in a container. It looks like the most recent versions of iris have removed some functions that ants uses, you may need to use an older version of analysis3. Version 23.10 shows fewer issues when running …

[image] Scott: ns of iris have removed some functions that ants uses, you may need to use an older version of analysis3. Version 23.10 shows fewer issues when running through its tests - errors in the lake filling routines are the only concerning ones. svn co https://code.meto If you need to…

Just bumping this now we have switched to the xp65 analysis3 environment. The latest version of analysis3 (25.04) has ants installed and this can be imported from a python/ipython interpreter. But I haven’t found an associated analysis3 Jupyter kernel with ants installed. I’ve tried analysis3-2…

Paul can you please clarify: the latest version of analysis3 (25.04) has ants installed I don’t see ants in the xp65 version of analysis3-25.04. On gadi I do: module purge module use /g/data/xp65/public/modules module load conda/analysis3-25.04 ipython import ants which cannot find ants. Do y…

Ok that’s weird. Earlier today I thought I could import ants into xp65. But now I just did this. $ module purge $ module use /g/data/xp65/public/modules && module load conda/analysis3 Loading conda/analysis3-25.04 Loading requirement: singularity [pag548@gadi-login-04 reanalysis]$ ipython Pytho…

@Paul.Gregory you are definitely not crazy… you were loading: Ants | Anaconda.org ANTs computes high-dimensional mappings to capture the statistics of brain structure and function We have new packages available for ANTs (The UK MET OFFICE one) but the way they are managing there dependencies makes…

Newer version of ANTS in analysis3 or other env on gadi?

FYI, ants is now released as a stand-alone containerised environment.
This will atomatically be aupdated with new ants releases.
