Dear EEGLAB list,

I have 14 channel EEG tool through which i acquired continuous signals. Now
i followed all the pre processing steps mention in EEGLAB tutorial, like
import EDF file>>Select channel location>> Remove baseline>> basic band
pass filter (0.1Hz to 40HZ)>> re-referencing channel data>> eye artifact
removal manually>> RUNICA>>
*i got 14 component from all 14 channels.*
Q: How to interpret the ICA component in EEGLAB, what are the steps for
analyses of ICA data?

Q: What color indicates in 2d, 3d topographic maps shown in Independent

Q: Can i analyze specific frequency band  and its power spectrum after ICA ?

Q: Is that any tool in EEGLAB which help me to correlate the specific band
power v/s cognitive change during tasks.

Any suggestions or any kind of help regarding these questions will be
highly appreciated.

Many many thanks
