Good Lord, I guess I wasn't thinking very clearly trying to use PATH as
a variable for something else. I changed to,

FILE_DIR=$(ls -d './'$SET'/'$FOLD'/'$FOLD'_anneal/'$PARAM_SET'/'$AN_SET)
echo $FILE_DIR

FILE_LIST=($(ls $FILE_DIR'/'*'out.txt' ))
echo ${FILE_LIST[@]}

and everything is fine. I guess it was a bash issue after all. Thanks
for checking that out.

LMH
