Sometimes there is an issue communicating with the Bayestar server executing the following code in serial quickly gathers the last problematic stars

for i in `grep "Response" isoclassify/direct/*/output.log | awk -F'/' '{print $3}' ` ;do eval `grep $i isoclassify-direct.tot` ;done 
for i in `grep "Response" isoclassify/grid-parallax-no/*/output.log | awk -F'/' '{print $3}' ` ;do eval `grep $i isoclassify-grid-parallax-no.tot` ;done
for i in `grep "Response" isoclassify/grid-parallax-yes/*/output.log | awk -F'/' '{print $3}' ` ;do eval `grep $i isoclassify-grid-parallax-yes.tot` ;done
