in the data/Makefile, you have this if clause ( in "features: target)......min=`$(X2X) +sf $${raw} | $(MINMAX) | $(X2X) +fa | head -n 1`; \max=`$(X2X) +sf $${raw} | $(MINMAX) | $(X2X) +fa | tail -n 1`; \if [ -s $${raw} -a $${min} -gt -32768 -a $${max} -lt 32767 ]; then \......Is there any particular reason why you are limiting using "lt" "gt" ? (instead of "le" and "ge")Many of my raw files are having +32767 as max and so are getting rejected from any further treatment.Why are you not using le and ge? ........please let me know.Thanks-Mahesh
