[Eeglablist] questions related to erpimage() function

[Tarik S Bel-Bahar]

Hello Akshay, Not sure if this will help, but it should get you past your
current block...Best wishes.

for erpimage, one should first take a close look, and try, the various
flags possible in the function.
Type "open erpimage" or "doc erpimage" or google erpimage to get the info
and then give those a try.
Some flags may be depreciated, and if so, a note in the eeglab bugzilla is
appreciated, if you can replicate the problem.

I would recommend using eegh to get the command line verson of the
pop_erpimage with "smoothing",
and then work with changing those flags as needed in the command line.
One solution could be: run pop_erpimage instead, ad add in flags for
erpimage into the pop_erprimage command.

for cbar, try plotting the image first, and then adjusting the colorbar
using matlab commands for modifying the colorbar, which you can easily
google search.
for example, search "change color bar limits matlab"
