I am using conform-gt from Beagle5 to align my input files to the reference. Conform-gt has successfully aligned the target chromosome files 1-23 to the reference using the same command below (with the exception of changing the chromosome number to match the reference, of course), but it has failed for chr2.
The two positions listed in the error below are not present in the target file, but are present in the reference file.
Does anyone have any ideas on why this error is occurring? Note: The reference file was downloaded from Beagle's website and has not been altered in anyway.
