hlaConvSequence function: No matching: 02:02

[arsangjang]

Dear Xiuwen,

Thank you so much for developing the wonderful HIBAG package.

I am currently using HIBAG to analyze the association between HLA and an outcome. However, I encountered an issue with the hlaConvSequence function, specifically an error indicating "No matching for HLA_DQB1*02:02." This results in missing sequences for the relevant samples, which leads to a reduction in my sample size.

Is there a way to resolve this issue to prevent the reduction in sample size? Any guidance or suggestions you can provide would be greatly appreciated.
