-### paf2aln.js: convert PAF to other formats
+### <a name="paf2aln"></a>Convert PAF to other formats
 
 Script [paf2aln.js](paf2aln.js) converts PAF with the [cs tag][cs] to
 [MAF][maf] or BLAST-like output. It only works with minimap2 output generated
 using the `--cs` tag.

+### <a name="sam2paf"></a>Convert SAM to PAF
+
+Script [sam2paf.js](sam2paf.js) converts alignments in the SAM format to PAF.
+
+### <a name="gff2bed"></a>Convert GTF/GFF3 to BED12 format
 
 Script [gff2bed.js](gff2bed.js) converts GFF format to 12-column BED format. It
 seamlessly works with both GTF and GFF3.
