I don't really see how you can have the relevant information for that format in a BED file. Paste some line so I can have a look. But you can most likely do the conversion with Biopieces www.biopieces.org) either using read_bed or read_tab:

read_bed -i file.bed |
rename_keys -k Q_ID,SNPID |
rename_keys -k S_ID,Chrom |
rename_keys -k S_BEG,Position |
write_tab -ck SNPID,Chrom,Position,AlleleState,Strand,SampleID1,SampleID2,SampleID3 -x

or something down those lines ...

Plink file also contains bed and bim file.

The thing is that one needs to recode the alleles from binary to additive and then convert it in to ABHU format, then transpose it taking binary markers name from bim file and sample id from fam file.

But then how to do it automatically? i mean by commands?

I hope this explains.

thanks
