Dear Alyson,

this issue was fixed some time ago. Download the latest revision of EEGLAB (13.1.1) or simply replace the following function.

Best,

Arno

Following what it says in the pop_erspparams description (see below), I entered a range for ‘Plot scalp map at time’ (topotime) and ‘Plot scalp map at freq’ (topofreqs) but keep getting the following error:
