[Gmod-ajax] wig-to-json.pl gives low resolution image and the values didn't correspond to the values in wig file

[CHAN, K. 1 [AG/7721] <ken...@mo...>]

Hi guys,
  I encountered a strange result when using wig-to-json.pl. The
quantitative track I got has a very low resolution and the values
doesn't seem like corresponding to the wiggle file.
  I attached the wiggle file and the resulted picture after applied the
following command:

./bin/wig-to-json.pl --wig
/bifx/apache/htdocs/gbrowse2/databases/te_viewer/testing/TS_76715_CG_R_C
overage.wig --out "event_data/TS_76715/" --key "Reads Coverage" --tile
"event_data/TS_76715/" --tracklabel Coverage

  I noticed that the above command didn't generate the 'tiles' directory
in the "event_data/TS_76715" as I specified. If I took out the tile bit
(--tile "even_data/TS_76715"). The tile directory appears in the data
dir. I tried to copy the tile dir to the "event_data/TS_76715" manually
but the resolution didn't change. May I ask what the generated "tiles"
directory is for? And do you have any idea how I can fix this problem of
low resolution. Thanks.

Regards,
Kenneth
