Yes, you must have all the subjects to precluster. Clustered components are common to all STUDY designs.
This is for consistency reasons because EEGLAB will be confuse if you have another design including this subject.

These files maybe corrupted and must be recomputed”. These warnings still appear even after recompute component measurement. I used the latest EEGLAB version for analysis.
