UCSC browser tract problem

[sarbashis]

Dear All,
I have generated wig file using igvtools of the alignment and I want to upload wig file to ucsc browser. I have added tract information at the begining of the line. File can upload successfully but in browser showing "no data" on the left panel. Any suggestion is highly appreciated. Few lines of the tract are given below

What do you mean no data on the left panel? I took a few lines from your example (you do not say what genome this is) and they display ok at UCSC.
