Hi,

I try to upload a sorted gff file to genome browser(human), but I keep get
warnings, then I did some test:
1. I found genome browser will work when gff file is sorted by chrID(first
column) and strand(7th column).

2. Does genome browser can only read one chromosome a time? since I found
following 2 example can be read separately but cannot be read if combine
them together
example 1:

chr21  TeleGene        promoter        10010000     10010100     900
  +
.           TG1

chr21  TeleGene        promoter        10020000     10025000     800
  -
.           TG2
example 2:

chr22  TeleGene        enhancer        10000000     10001000     500
  +
.           TG1

chr22  TeleGene        promoter        10010000     10010100     900
  +
.           TG1

chr22  TeleGene        promoter        10020000     10025000     800
  -
.           TG2

chr22  TeleGene        promoter        10000000     10025000     300
  -
.           TG2

Is my understanding correct? Is there a way that I can upload all my data at
one time?
