File doesn't have the given chr_chr map

[yizhang-zoey]

Hi.

When I use the following command to convert a hg19 .hic file to a hg38 .cool file:

HiCLift --input $INPUT --input-format juicer \
--out-pre $OUT_PREFIX --output-format cool \
--out-chromsizes $REF \
--in-assembly hg19 \
--out-assembly hg38 \
--chain-file $CHAIN

I got the following screen output:

File doesn't have the given chr_chr map 1_25
File doesn't have the given chr_chr map 2_25
File doesn't have the given chr_chr map 3_25
File doesn't have the given chr_chr map 4_25

What's the meaning of File doesn't have the given chr_chr map? Does it mean there is something wrong with my input file?

Thanks
