Add option to pad locus tag number with zeros

[bartns]

Thanks for this tool it can be very convenient! I had some augustus like gff3 file that needed be converted. But I personally like to see locus tags numbering padded with zeros. So I added it and made it an option to the script. It works only for the newly created locus tags numbering.

It takes the total amount of features for the padding amount.
For examples, when there are 9999 features it will increment the locus tags as 0001,0002,etc to 9999.

It worked in my case and didn't seem to fail any of the tests.
Feel free to do whatever you like with it.

Kind regards, Bart.

May I ask you if you use EMBLmyGFF3 for conversion only or for submitting data to ENA?
Just for your information, in the case of submission the locus_tag will be anyway overwritten.

Yes, for submission in this particular case and I did not realize this... Thanks for heads up. But how does that work? What will ENA do with it? The numbering method is quite crucial in case of locus tags. If I use for example a tool like bakta it will create locus tags with increments of 5.

I think it would be nice to have the most closely resembled version of the submitted locus tag before submission.

Sorry my mistake they just add a prefix to the locus tag, so it should be fine.
This prefix may be choosen when registering the sample, otherwise they will give one by default.
