Hello Patrick,

I have got an error in plotting by u-bh383 for 'lba'. The job.err files says:

File "/home/users/azin/miniconda2/envs/iris_env/lib/python2.7/site-packages/iris/cube.py", line 2147, in getitem

cube_data, keys)

File "/home/users/azin/miniconda2/envs/iris_env/lib/python2.7/site-packages/iris/util.py", line 720, in _slice_data_with_keys

raise IndexError?('Cannot index with zero length slice.')

IndexError?: Cannot index with zero length slice.

This iris_env was OK with 'mead' sites, but it seems it has a problem with 'lba'.

I have also attached the screenshot.

All the best,

Hi Azin
Your log file ~azin/cylc-run/u-bh383/log/job/1/make_plots/01/job.out suggests that it failed either during the LBA_FNS FLUXNET site plotting or on the next FLUXNET site. Can you first make a backup copy of your azin/roses/u-bh383/bin/list_sites_lba.txt file and then try running your suite again without the LBA_FNS site by removing that site from azin/roses/u-bh383/bin/list_sites_lba.txt? If that doesn't work, then you might try deleting the next site, which is LBA_PDG.

The other thing to do is to try to figure out how LBA_FNS is different from the other LBA FLUXNET sites. You can look at the input data, to see if there are any temporal gaps in the data, etc.

Hello Patrick,

I don't have any problems anymore, but I can not remember exactly how the problem was solved.

All the best,
