Hi I am running the ucsc liftover(hg18 to hg 19) for a bed file(the bed file has no header) My command is
./liftOver hg18ToHg19.over.chain.gz ABCD.bed ABCD_hg19_processed.bed ABCD_unlifted.bed
However it gives following error:
Reading liftover chains Expecting at least 12 words line 1 of ABCD.bed
Is this a common error? If so what is the reason for the same?
