I am not an awk syntax expert but AFAIK you don't want to split up the
awk program string into separate arguments. Quote the entire program
into one string argument. I think that is the root of your problem.
Your example shows an "if" in program argument one and the rest of the
program in program argument two.

I would do that this way using pattern-action pairs where the pattern
acts as an if statement. It just seems the most awk-ish way to me.
gawk '$8<0.001 {print "SNP:" $2 " P="$8}' Batch_Call_dev-bs.model.P1.model
I tested with this:
printf "1 one\n2 two\n3 three\n" | awk '$1<3 {print $0}'
1 one
2 two
But using the awk if control syntax in the awk program itself also
works okay. Here is a test using it:
printf "1 one\n2 two\n3 three\n" | awk '{ if ($1<3) {print $2;} }'
one
two
Hope that helps,
Bob
