Batch Correction

MetaboAnalyst currently supports nine well-established methods (ComBat, EigenMS, QC-RLSC, ANCOVA, RUV-random, RUV2, RUVseq, NOMIS and CCMN) for batch effect correction.

  • Batches can be uploaded as multiple individual files or a single merged file. In the former case, only overlapped features across all batches will be used. In the later case, batch information should be provided in the table. More details are provided below for each scenario;
  • The automated (default) will return the results with least distance among batches.
  • EigenMS is not supported for large files (> 5M), please use MetaboAnalystR in this case.
  • QC-RLSC requires injection order (only available for 'Upload A Single Merged File')
