Two tracks circos bar plot

Introduction
circos plot is very popular in high throughput sequencing papers. It depicts peaks, genes, GC content and many more information along chromosomes with different circles.
Input data instructions
Input data contain 4 columns: the first column is chromosome, the second column is start coordinates, the third column is end coordinates, and the last column is values (such as fold change, expression)
Examples from papers
1, show up and down regulated genes.
Input Outer track input data
Inner track input data
Output

1) How to plot?
1, Prepare data
2, Open with excel, and change into the same format as the example
3, Copy and paste data into the input frame
4, Select parameters
5, Submit and download figure files

2) Why NO figure generated?
Script need strigent input format, please read the instructions and examples carefully.
