Genomestudio2 output to use in Tassel5?

Hi, I got a genotyping data in Genomestudio 2.

I want to export the data to use in Tassel5 for PCA, LD, and GWAS analysis.

The problem is, when I load the data into Tassel5,
it is put in as a numerical data, not genotype data.
I read an user manual but it’s not helpful.

Is there any way to convert data so that I can use in Tassel?

Thank you.
