[Eeglablist] questions related to erpimage() function

[Makoto Miyakoshi]

Dear Akshay,

> 1. cbar: How to define the high-low limits of 'cbar'? Could I set these
limits arbitrarily? For example, say, I want to look at +/-5 uV range
irrespective of presence of higher amplitude peaks (say 10 uV).

Yes, it determines the color scale.

> However, It seems that I can't set the avewidth anything greater than '1'.

You may have a problem in either your data length or number of epochs. How
many epochs do you have now?

Makoto
