 Note that RSEM does ** not ** support gapped alignments. So make sure
 that your aligner does not produce alignments with
-intersions/deletions. In addition, you should make sure that you use
+insertions/deletions. In addition, you should make sure that you use
 `reference_name.idx.fa`, which is generated by RSEM, to build your
 aligner's indices.
