Hi:
I am a new person here. I find some chip-seq data from GEO database, it is showed as below. want to know how to make the data more visible. like some chip-seq data shown in IGV? Thanks.

This a list of peaks, not a ChIP-seq track. Could you post an example of what you mean by ChIP-seq data shown in IGV?
Hi jotan:
I do not know what is the meaning of "not chip-seq track", I downloaded the data from geo database, and it should be Chip-seq data, but has been analysed by the author. The data are shown in a picture in IGV, and can be searched by gene symbols. I do not know how to show the picture here. Thanks.
Here is an example of a peak track and its corresponding sequencing track viewed in UCSC
The top gray blocks are a list of peak coordinates, similar to what you have in your example.
The blue track underneath is a representation of sequencing reads.
It is commonly stored as a wig/big wig file
