[Eeglablist] error in cleanLineNoise

[Anna Kasdan]

Hi all,

I am getting the following error when trying to run cleanLineNoise
from the PREP pipeline. I've downloaded the version 0.55.3, and have
also tried installing/reinstalling both through the GUI and not to
understand if this is a version error, which it seems not to be. Is
this related to some other matlab dependency, or something else?

Thanks very much,
Anna
