GCTA 1.02 on MAC

The .grm.bin format was introduced with GCTA 1.1, so GCTA 1.02 does not support it. Use the .grm.gz format instead.

When I try to estimate the genetic variance explained by all autosomal SNPs (case-control) I get the following:

Options:
--reml
--grm test1
--pheno test.phen
--mpheno 4
--prevalence 0.03
--qcovar test.qcovar
--covar test.covar
--out test


Reading IDs of the genetic relationship matrix (GRM) from [test1.grm.id].
3171 IDs read from [test1.grm.id].
Reading the GRM from [test1.grm.gz].
Pairwise genetic relationships between 3171 individuals are included from [test1.grm.gz].
Reading phenotypes from [test.phen].
There are 4 traits specified in the file [test.phen].
The 4th trait is included for analysis.
Nonmissing phenotypes of 3721 individuals are included from [test.phen].
Reading quantative covariates from [test.qcovar].
2 quantative covarites of 3171 individuals read from [test.qcovar].
Reading discrete covariates from [test.covar].

Error: each row should have the same number of columns.

The test.covar file exists of 3 columns in each row: familial id, individual id and gender. Perhaps someone knows what the problem is? BTW, it works without the extra covariate gender (test.covar).
