# make bigwig file for genome browser visulization
# usage
# makebigwig.sh <infilename> <outfile> bedorbam sorted genome strand -split
# input file types: *.bed, *.bam

# use of output: move to public_html and visualize in ucsc genome browser with the following:
# track name="xxx" color=0,0,255 type=bigWig bigDataUrl=http://rous.mit.edu/~wuxbl/xxx.bw
