multiple sequence extracted for one gene

[alexwu66666]

Hi there,

I am using the scripts provided to extract some regulatory sequence of genes using genome file, while I received multiple sequences for one gene, and not sure why this happened, the issue is as below:

Could you please help explain the reason or provide any approaches to clean the sequences? Thanks a lot!
