tl;dr: anybody knows whether this info is stored (or not) and where? thx

Queridos fieldtrippers,

I am trying to find where the info about the amount of variance that each
component explains is stored (if it is) after running ft_componentanalysis

I know the interesting data is in two fields: topo + unmixing. May it
happen that I am supposed to derive the variance explained by each
component using some kind of mathematical sorcery and this values.

If my question is too naive, I apologize, I think that the channels
(actually 'components') of the output structure are sorted in descending
order of variance explained during the call to the function, I searched
there and in ft_databrowser unfructiosly. Also parsed the mailing list
(there are two other answered questions
