correlation matrix

[misbahch6]

Hello,

Thank you for developing NGSCheckMate tool.

I have used this tool to compare two bam files (obtained from different cells of the same individual):
python ncm.py -B -l bamlist -bed SNP/SNP_GRCh37_hg19_wChr.bed -O final-output

In the output_all I get the following output:
Rhdkt-8 unmatched Rhdkt-9 0.3358 32.88

However, in the output correlation matrix I get the following output:
Sample_ID Rhdkt-8 Rhdkt-9
Rhdkt-8 0 0
Rhdkt-9 0 0

Should not it be 1 in the diagonal ? I don't know what I am doing wrong here. Thank you in advance for helping me.
