Empty avinput files corresponding to multisamples in ANNOVAR

Hi, I was using ANNOVAR to convert multi sample vcf file to avinput files (annovar format). I used this command :

sudo perl convert2annovar.pl -format vcf4 -allsample -include multisamples1000gPhase1.vcf > multisamples1000gPhase1.avinput

But I got empty avinput files corresponding to 1092 samples, the original vcf file was around 26GB. Why did this happen??? Can someone explain?

annovar annotation 1000g

You should never need to use sudo to run scripts unless the scripts absolutely need admin access (which 99% of what you do won't need). What happens when you don't use sudo?
