Debug the No File Found error

One of the most common errors comes from a bad dataset definition in datasets_setup.py.

It typically triggers this error:

		error    : "No file found for ds('IGCM_OUT%CM607-LR-pdCtrl-01xx%tas%2000-2009%global%/ccc/store/cont003/thredds%p86caub%IPSLCM6%*%pdControl%*%Analyse%*%monthly%2000_2009%*')"

Use set_available_period_ts_clim.py to debug

A convenient way to debug this kind of situation is with set_available_period_ts_clim.py . If you work on you comparison standard_comparison, run:

python set_available_period_ts_clim.py standard_comparison/ tas

If it returns the upper error, have a look at the log above the error message that shows the patterns CliMAF is actually using to locate your files:

Select the pattern that is the closest to the one you are supposed to target.

1. Pay attention to the presence of 'IGCM_OUT' in the path: CliMAF checks for patterns with and without it.
2. do you want to work on 'Analyse' or 'Output' files?
3. Copy the pattern that 'should work' and try to a ls on it:

ls /ccc/store/cont003/thredds/p86caub/IPSLCM6/*/pdControl/CM607-LR-pdCtrl-01xx/*/Analyse/*/CM607-LR-pdCtrl-01xx_????????_????????_1M_t2m.nc

ls: impossible d'accéder à /ccc/store/cont003/thredds/p86caub/IPSLCM6/*/pdControl/CM607-LR-pdCtrl-01xx/*/Analyse/*/CM607-LR-pdCtrl-01xx_????????_????????_1M_t2m.nc: Aucun fichier ou dossier de ce type

Simple checks:

• delete part of the path/filename to track the error, like:

ls /ccc/store/cont003/thredds/p86caub/IPSLCM6/*/pdControl/CM607-LR-pdCtrl-01xx/*

• on Ciclad, check that the connection to the thredds is ok:

ls /ccc/store/cont003/thredds

Keep digging, you will find the error :)!
