RSEM bam

[MarcelloMalpighi]

Hi,
I am curious about the discrepancy in read counts between *.transcript.bam and *.genes.results from RSEM. The counts were calculated using the following code.

>samtools view -F 4 SRR3936136.transcript.bam | awk '{print $1}' | sort | uniq | wc -l
>932000
>awk '{if(NR!=1)sum+=$5}END{print sum}' SRR3936136.genes.results
>931068

Additionally, could you clarify the difference between *.transcript.bam from RSEM and *_Aligned.toTranscriptome.out.bam generated by STAR?
Thanks in advance.
