Introduction:
This tool takes multiple peak tables as input and
merges them together. The outputted peak table will have more samples and
compounds. If a compound exists in some but not all tables, it will be filled as
NA in missing position in the final merged table. If same sample names exist in
different tables, their common compounds will be averaged and outputted in the
final table.
Input files:
1.
Multiple peak table files in
Tab-delimited txt format, with the first column as the compound identifier and
the others as samples.
For example:
