Segment Mapper - Make a graphic chromosome map from a CSV of overlapping segments

This program will make a chromosome web page chart from a CSV file for segments mapped for up to 40 individuals.

These are the colors that are used, they are assigned in the order in which your matches appear.
#0000FF	#99ccff	#ff0000	#ff9955	#00cc33	#008800	#ffff99	#bb4466	#aaffff	#00aabb
#660000	#ffdd66	#003366	#00ffcc	#9911bb	#cc99ff	#ff99cc	#FFE3F1	#ff66ff	#cc33bb

INSTRUCTIONS Click here for detailed documentation for this tool in a new window
The input to this program needs to be a CSV such as an export from 23andme or Family Tree DNA or DNAgedcom. The column headings, in any order, on the first line of the file must be (N.B. case sensitive): Comparison, Chr, Start point, End point, cMs, The "Comparison" column should contain a name. "MatchName" will also work as the column heading for the names. WARNING if the CSV is too large the upload will fail with no error message.

Programming is how I make my living so a small donation of $5 or $10 would be most appreciated, if you find this tool useful.
