The current approach creates separate files per channel. If we analyse 10 samples with 3 channels this creates the slightly akward situation that we have 3 matrix files with 10 samples each. I think the more natural way is to have a single matrix file with 3x10=30 columns/samples (like DIANN).

How should the merged files be shaped? - 30 cols everywhere <-- chosen - 30 cols pg, channel col below - 10 cols + channel col Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
