Hello,

I am trying to calculate hertibility after running a binomial gblup model. I'm using a standalone ASReml4 on a Mac.

The model runs to convergence but when it gets to manipulating the variance components I get the error below

Failed to interpret line: Reading pedigree file M048_Dead_and_Alive_Pedigree.

Failed to interpret line: Reading pedigree file M048_Dead_and_Alive_Pedigree.
txt: ski
Program to calculate functions of variance components from ASReml output.
Reads <xx>.asr, <xx>.vvp and <xx>.pin, writes <xx>.pvc
Usage ASREML -P <xx>[.pin]
or ASREML -P<xx>[.asr] <xx>[.pin]
<xx>.pin gives the function of components to be calculated
The input file may have a different extension (not PIN).
Fields may be TAB SPACE or COMMA separated.
" characters are ignored; Anything after # is ignored
Input consists of lines of three types
Each line consists of a code in column 1 (P, H or R),
a label and a list of arguments (space separated)
P label c calculates c'v, Cov(c'v,v) and Var(c'v)
where v is the existing variance components
c is coefficients for a linear function
It is used to construct linear functions of variances
NB each P line extends v by one term
H label n d calculates v(n)/v(d) and Var[v(n)/v(d)]
i.e. is used to calculate heritability
R label a ab b calculates v(ab)/sqrt[v(a)v(b)] and its
variance (i.e. a correlation)
[/i]

Making a separate pin file resulted in the same error.

I can see that there is a problem reading the asr file, but I can't understand why that would be since the model ran to completion. Any advice on how to fix this is greatly appreciated.

Thanks,

Joshua
