Cuffdiff - Error in running cuffdiff by using the merged transcriptome assembly along with the BAM files from TopHat

hello everyone, I ran cuffdiff using following command:

cuffdiff -o ./diff_out -b ./genome.fa -p 7 -L c1,c2 -u ./merged.gtf \
./accepted_hits_S1.bam,./accepted_hits_S2.bam,./accepted_hits_S3.bam ./accepted_hits_S4.bam,./accepted_hits_S5.bam,./accepted_hits_S6.bam,./accepted_hits_S7.bam,./accepted_hits_S8.bam,./accepted_hits_S9.bam,./accepted_hits_S10.bam,./accepted_hits_11.bam,./accepted_hits_S12.bam

And the output was:

this is the code.
