Usually this will be because it is a Pfam family for
which there is too little sequence data (Pfam-A seed alignment or
corresponding DNA) to generate a meaningful PANDIT entry, or one that
has not yet been incorporated into PANDIT (particularly soon after new
Pfam releasescompare PANDIT and Pfam release numbers). Possibly
it is a family that has been removed from Pfam. Check the above link to
Pfam for further details. If this does not resolve your problem, or you
think there is some error, please contact the PANDIT team at firstname.lastname@example.org.
