IUPAC code in TE database

[Yiguan]

Hi,

I am using teflon_prep_custom.py to annotate the reference genome. In the TE database -l I am using, I found some letters rather than ATGC in the fasta file. I guess they are IUPAC code for some ambiguous bases.
I am wondering if teflon works with IUPAC code. Currently, it didn't raise any errors or warnings when I run teflon_prep_custom.py with IUPAC.

Thanks,
