Closed:What is the best database ID to map a protei ID list ?

Question

[mehmetazizyirik]

Hi guys;

I wanna map all of the protein IDs I have to a unique ID type. I tried to map them to pubchem ID however while doing that I received some errors; so is there any other option to map all of them to another ID type ? However the task should be completed programmatically not manually.

All the Best; Mehmet Aziz Yirik
