this is the swift standard primer file. You are a bit off in your interpretation of the columns (seems like you missed one as there are 12 columns, not 11 which threw everything off):
Chromosome
Target Start
Target Stop
Target Name (change which affected everything downstream in counting)
5' Primer Start
5' Primer Stop
5' Primer Name
3' Primer Start
3' Primer Stop
3' Primer Name
5' Primer Sequence
3' Primer Sequence
To convert to a BEDPE describing the primer locations, you only will need the first 4 columns 1, 5, 6, 8, and the9 (and optionally 4). The last letter of the Region name for the denotes the strand orientation of the region. For example Region 1 has _F denoting forward or (+) strand for BEDPE usage, while region 2 has _R in name denoting reverse or (-) strand for BEDPE. Putting all this together, you can convert to BEDPE with:
$ awk -v OFS="\t" '{
o=".";
if($4~/_F\//){
o="+"
}
else if($4~/_R\//){
o="-"
}
print $1,$5,$6,$1,$8,$9,$4,".",o}' foo.masterfile
