Creation of a variable number of collections

[aepetit]

Hi,
I am creating a galaxy tool and I need to get as output a number of collections that depends on a value contained in an input file. I got the value from my file and did a for loop using this value. However, I still get only one collection as output. Is it possible to get a variable number of collections? And if it is possible, how can I do it?

Hi @aepetit,
unfortunately, this is not possible.

Thanks @gallardoalba, I managed to work around the problem by using nested collections but the solution is not perfect.
