Can not locate class RemoveStrayHairs

[MeHelmy]

I had an error saying: it could not locate the class RemoveStrayHairs which is in src when I compile it javac RemoveStrayHairs.java it worked.

Then I had another issue in :
$EXTRACTHAIRS --mbq 0 --bam $LONGREADSBAM --VCF $PHASEDSNPS.prehairs --out $OUTPREFIX.hairs

It crashes because lack of memory my node is 50G can I control threads? Or how I can make it work?

Finally:
if [ ! -r $AS.raw.tgz ] then echo "tarring up alleleseq" tar cvzf $AS.raw.tgz $AS fi
always did not work. I used -cvzf and -C $AS yet did not work. can I comment it?
