Add a serial number to any Feature Qualifier.
You can select Qualifier to be serial number.
Normally, users can not register their original qualifiers, but you can create your own original qualifier that is used only when adding sequential numbers.
Sequential numbers consist of prefixes + sequence numbers, and consecutive numbers are further generated with a starting number and an increment.
The features that are subject to the sequential numbering are added in order from the one closest to the base position of the genome base position.
Not only features belonging to one type of feature key, but also features belonging to multiple feature keys can be mixed and added sequentially.
Sequential numbers can also be added for narrowed objects such as search results.
Sequential numbers can be added with the following search function.
