I am stuck at this step of the coursera course project.
step 7: identify polymorphic sites - using FreeBayes tool (version: 0.4) to identify polymorphic sites base on hg19 genome
ERROR(freebayes): could not find sample matching read group id Mother
ERROR(freebayes): could not find sample matching read group id Father
ERROR(freebayes): could not find sample matching read group id Father
ERROR(freebayes): could not find sample m
How should I solve this issue ?
