[Bioc-devel] seqlevelsStyle on alternate chromosomes

Hi Michael,

Seems like seqlevelsStyle<- between e.g. UCSC and NCBI does not work
outside of the "standard" chromosomes. Since GRCh38 (NCBI) and hg38
(UCSC) are the same assembly, we could probably implement a complete
mapping, right?

Unfortunately, the seqlevelsStyle() getter and setter were designed
from the very beginning to handle only the standard chromosomes.
Changing this is on the TODO list but didn't happen yet because it
requires a complete refactoring. In the mean time, see
?fetchExtendedChromInfoFromUCSC for how to map GRCh38 seqlevels to
hg38 seqlevels.

H.

Michael
