Smartrel does not yield any output

Hello,

I am trying to use smartrel to find related individuals in my data. Unfortunately, I get no file of pairwise correlation coefficients. In my log file, I can see those who were above the set threshold, but there is no output file. Here are my scripts:

smartrel.perl

#!/usr/bin/perl

$ENV{'PATH'} = "../bin:$ENV{'PATH'}";

$command = "../bin/smartrel";
$command .= " -p par.smartrel > smartrel.log";
print("$command\n");
system("$command");

par.smartrel

genotypename:    data.geno
snpname:         data.snp
indivname:       data.ind
outputname:	 data_rel.coef
numeigs: 	 1
relthresh: 	 0.10
numoutlieriter:	 0
numthreads:	 32

I would add that I get no output file no matter the paramenters set in par.smartrel. Also, it looks like smartpca parameters can go inside smartrel's. Does this apply to all params or just some?

Could you please help me with this issue?

Best,
Andrei

Start by reproducing the command from smartrel.perl with par.smartrel and inspect smartrel.log alongside the expected data_rel.coef output. Trace the smartrel entry point to determine why threshold matches produce no output file and verify which smartpca parameters are accepted; done means the documented configuration produces the expected coefficients file or clearly reports invalid parameters.
