Hello Ranawaz, there should be an easy fix to your problem. Notes below:


Overall, however, you should try your best to know/check what adjust is
doing, although many researchers trust algorithms a lot these days. If you
have not had a chance to, I recommend first reviewing the eeglab tutorials,
videos, and web pages about ICA and ICA rejection. Overall, unless you have
hundreds of ICA decompositions, try using a combination of automatic and
human IC selection.

This does not seem to be a problem with adjust. It seems to be a problem
with your artifacts perhaps not being properly isolate. Make sure you are
familiar with what the artifacts look like in the continuous data.

Check that you properly cleaned the data before ICA. See Makoto's pipeline
about eeglab steps for some general recommendations for beginning users.

*Not all artifactual ICs are removed, it is still an imperfect science.
*if you are a newbie with ICA, you can train yourself here:
This should be a very useful resource for you.

Also, if you haven't had a chance to, show yourself everything works in
your setup by using and removing ICs from the eeglab tutorial datasets.

also, check that you are correctly updating the EEG structure and saving to
file as necessary, just type eegh to get the commands that are being run
when you practice your steps first via the eeglab gui.

***also check you are using recent eeglab update, recent matlab, and recent
adjust plugin.

**see also a wide range of other ICA processing plugins mentioned on
