Operation

Select the old and new genome assemblies from the drop-down menu, and input your regions, the converted coordinates will be shown in the right panel.

You can input single positions like this (one position per line):

A01	10000
A01	20000
A01	30000

You can also input genome regions like this (one region per line):

A01	10000	10100
A01	20000	20100
A01	30000	30100

Chain files

The genome coordinates conversion process is based on LiftOver.

If you want to convert any two assemblies other than the provided ones (thinking that there are hundreds of combinations between multiple cotton genome assemblies!), you can use pychain to generate chain files by yourself, and then use liftOver to do the conversion.
