Hi, I am using cuffdiff for the Differential Gene Expression. Upon running the command, I see this problem. I have only three samples there is no replicate but my data is running accurately. I am confused, either it will cause a problem in the future or not?

Outputs:

No conditions are replicated, switching to 'blind' dispersion method
Inspecting maps and determining fragment length distributions.
Modeling fragment count overdispersion.

Hi, you will not be able to publish this data, in my opinion. Having just 3 samples and no replicates is 'problematic'. Can you please show the commands that you are running? Thank you in advance, Muhammad

Hi, I am sorry for the late reply. I understand my samples are not enough but this is what my professor said to do. I used this command.

cuffdiff -o diff_out -b genome.fa -p 20 --library-type fr-firststrand -L b73,f1,mo17 -u stringtie_merged.gtf b73.bam f1.bam mo17.bam

Great, and can you share some of the output? The message that you showed (above) seems to be a warning message, not an error.
