I encountered an issue when using. gds files to construct trees:
nohup: 忽略输入
载入需要的程辑包：gdsfmt
SNPRelate -- supported by Streaming SIMD Extensions 2 (SSE2)
[1] "Directory is created successfully!"
Individual dissimilarity analysis on genotypes:
Excluding 1,688,519 SNPs on non-autosomes
Error in .InitFile2(cmd = "Individual dissimilarity analysis on genotypes:", :
There is no SNP!
Calls: snpgdsDiss -> .InitFile2
停止执行
How should I solve it？by the way,my code is:

Thank you very much!!!

Today I found the solution. Change the name of the input chromosome to something like 1、2、3, and add an ID (similar to 1_259，chromosome 1 and position 259). I'm not sure if the ID needs to be changed, but the chromosome name must be changed, and adding the ID won't be wrong either
