Hi All,

I am new of Galaxy. I want to visualize my short mapping results in the browser.

I uploaded my .wig file which has format as this, (first column is position, second is the read soverage of that position)

variableStep	chrom=Chr1
4	1
5	1
6	1
7	1
8	2
9	3
10	3
11	3
12	3
13	3
14	3
15	3
16	4
17	4
18	4

But it comes an error
Couldn't open /galaxy/home/g2main/galaxy_main/tool-data/shared/ucsc/chrom/arabidopsis.len ,
No such file or directory

Does anyone know how to fix this?
Many thanks!

Best,

Peggy
