I'm trying to simulate binary phenotypes from the 1000 Genome Phase 3 datasets using gcta64 --simu-cc, but no success. Everything seems to be going well, but in the end I get:
Error: can not open the file [] to read.
An error occurs, please check the options or data
And the log shows:

Here's the commands I'm using:
# Convert the VCF to plink format:
$ ./plink2 --vcf ../../ALL.phase3.biallelic-only.vcf.gz.10kSNPs.vcf.gz --make-bed --out ALL.phase3.biallelic-only.vcf.gz.10kSNPs
# Try to simulate the phenotype:
$ ./gcta64 --bfile ALL.phase3.biallelic-only.vcf.gz.10kSNPs --simu-cc 500 500 --simu-hsq 0.5 --simu-k 0.1 --simu-rep 3 --out ALL.phase3.biallelic-only.vcf.gz.10kSNPs
Here's the whole steps with the outputs:

I'm opened to use other tools if you have any recommendation. Not sure, but looks like Plink doesn't do that (you can simulate phenotype as long as you also simulate the genetic data as well...)
