CNVnator : Error message Please Help!

[KYR]

I typed the following in unix and at step 3 CALCULATING STATISTICS CNVnator output an error message.. I have no clue what does it mean..

Here is what I typed :

./cnvnator -genome mm9 -root /home/chr1-bam1.root -chrom chr1 -tree /home/chr1-bam1.bam
./cnvnator -genome mm9 -root /home/chr1-bam1.root -chrom chr1 -his 100 -d /01.Reference/mm9
./cnvnator -root /home/chr1-bam1.root -chrom chr1 -stat 100

And Here is the output on the last step CALCULATING STATISTICS :
