Is it possible to go back to a vcf from a genotype matrix?

I was given a genotype matrix which was originally in a genalex format. I was able to convert it other formats such as STRUCTURE but I was not able to convert that to a VCF (using PGDSpider), because chromosome and location information are required. I do not have them.

Am I trying to do something that should not be done? That cannot be done?

It sounds like there is a lot of information that you don't have, but which is required for a vcf file. If you could get access to the raw data getting a vcf would be easy, but I don't think your genotype matrix will allow you to create a vcf.
