[Genome] Question regarding EST panel

[Bishwanath Chatterjee]

HI
 I am looking into EST data for gene RECK chr4:43,896,700-43,965,620 and
find some of the EST shows double line after single line and also mRNA
panels have different color. I will appreciate if you let me know how to
read the double lines or color displays and what it exactly mean?
