Differences between .results file and .cnt file #104

Hi,

I am using RSEM v1.3.1 to generate count matrix files for DEG analysis. I ran:

RSEM-1.3.1/rsem-calculate-expression \ ~/CV/1_8.fq.gz \ ~/CV_genome/CV \ ~/CV/RSEM/1_8

the resulting count file looks like:

12815220 32705307 881233 46401760 15576149 17129158 17238217 126285194 1

From which I understand there were 32,705,307 alignable reads.

However, when I load the resulting 1_8.genes.results file into R and sum the total number of reads I only have 30,176,704 reads for that sample.

Any idea why this value would be lower than the number of alignable reads?

Thank you, Kevin
