[Eeglablist] ICA - Mimimum # of Data Points

[Janelle Crouch]

Is it reliable to use ICA with fewer data points than called for in the
*ch*2x30 *formula?  With 256 sensors, it would be difficult to collect such
a large number of data points as our acquisition time is about 7 minutes.
If ICA results from a lower number of data points would not be reliable,
can anyone suggest their preferred method of artifact detection and removal
that does not use ICA?

Thank you,
