You need to hop all over the source tree like a frog on a griddle to get things done...

A BED track description for a custom SNP track

The .bed file has lines like this:

Load the .bed file into a custom track called Ill550v3 Note the .bed file must have NO browser or track lines - otehrwise hgLoadBed will barf

Adjust your trackDb.ra file

I'm working (eg) on meme in

/home/rerla/hg18/kent/src/hg/makeDb/trackDb/human/hg18

I add these settings - they seem to work the way I want, allowing the name field from the .bed file to appear in full view:

track Ill550v3
priority 20.1   
shortLabel Illum550kv3           
longLabel Illumina 550k v3 snps
visibility pack
type bed 9 .          
color 255,0,0   
group varRep                 
thickDrawItem on

Recompile the trackDB

make alpha DBS=hg18
