Feature Request: Option to subset reference SNPs to query file positions before training

[weekend37]

Would enhance model performance in most cases and avoid disaster where imputation has not been performed.

Hi. I am having this issue when training the model from scratch after filtering the snps in the query file. I am not sure what to do.

After building the model, I get this error when doing the inference in the query samples.
Any advice is appreciated.
