YC and YD tags

[YanniWang-g]

Hello, could you tell me what the YC and YD tags mean? I need to use an analysis tool compatible with Bismark, and perhaps I can generate the XR and XG tags from these two tags. This is very urgent, and I am eagerly awaiting your response

So I have been looking into this and from the source code

        # first letter of chrom is 'f' or 'r'
        direction = aln.chrom[0]
        aln.chrom = aln.chrom[1:]

        assert direction in 'fr', (direction, aln)
        aln.other.append('YD:Z:' + direction)

It seems YD represents what XG tag in Bismark and YC is what XR tag represent.
