Hello Bioconductor, I have SNP data in HapMap format and would like to read it in R as snp.Matrix for further analysis. But I have problem to read my hapmap data using function read.HapMap.data {snpMatrix} library(chopsticks) library(hexbin) snp_data="ftp://ftp.gramene.org/pub/gramene/CURRENT_RELEASE/data/diver si ty/data_download/hapmap_plink_files/diversity_rice32.bgross.chr12.hapm ap " result <- read.HapMap.data(snp_data) error:Unexpected header: rs# alleles chrom pos strand assembly#..... conversion failed. I have tried to clean up the header with simple names, but it did not work either. Any idea how to solve it? Thanks! Xiaolian [[alternative HTML version deleted]]
