Getting truncated PVAR file when converting BGEN file

[Thon de Boer]

I am converting the UKBB GEN formatted file for use in PLINK2 to PGEN format, but I am consistently getting truncated files that seem to end in the middle of a line...

bluebee@bbench:~/ukbb/genotypes$ tail chr21.pvar

21      48043815        rs77375664      T       G

21      48043904        rs537966753     A       G

21      48043934        rs111552696     A       G

21      48044021        rs571687629     G       A

21      48044043        rs545365966     C       T

21      48044047        rs9984956       bluebee@bbench:~/ukbb/genotypes$ wc chr21.pvar

 1259002  6295013 35520512 chr21.pvar

This is the command line I used

plink2 --bgen ukb_imp_chr21_v3.bgen ref-first --sample ukb57143_imp_chr21_v3_s487296.sample --out chr21

I tried the latest release as well as stable alphe 2.3...

Any ideas?
