How can I update a linelist

[BenediktBurger]

I downloaded transitions for one isotopologue with the name "h2o" (btw, it is good to explain the parameters in the docstring, I did not know, what the parameter "llist" did).

How can I replace the previous line list with a new one, which contains, for example, more isotopologues or another wavenumber range? I deleted the files "h2o.data" and "h2o.header", but fetch_transitions still raises "linelist h2o already exists".

Hi Benedikt,

Currently the linelists are immutable. This is a temporary measure to ensure the data provenance chains are always correct. Now there two options: either use different name, or delete the old linelist from the database, for instance, using the SQLAlchemy API:

session.delete(linelist)

Best wishes,
Roman

Hello, I would like to ask how this problem is solved, where is the code
session.delete(linelist)
added

I deleted the files "h2o.data" and "h2o.header", but fetch_transitions still raises "linelist h2o already exists".After I delete the local file automatically generated in the running, it can run correctly.
