fix bug when no noise found

[edickie]

right fix module will not generate an output dies if no noise ica's are identified (i.e.all components are signal).
We should change this to output a copy of the input in this case

for outdir in ls -1d *_5*; do
fixfile=${outdir}/RST/SESS01/fake*feat/fix4melview_abide_USM25_thr20.txt
if [ tail -1 ${fixfile} | wc -c == 3 ]; then;
echo ${fixfile}
fi
done
