Hello,

I have a question about analysis using DESeq2.

I have three samples of different time points without replicates. I want to check the genes whose expression level changes over time.

I have studied time series analysis but I know that this analysis requires a comparison target such as control (untreated vs treated). I have control samples with replicates but these are not samples of different time points.

Is there any way to analyze using these continuous variables? Or Is there any commendable method of analysis using DESeq2?

The easiest way to get help is to fully describe your dataset. How many time points? How many control samples? These details matter in what we recommend.

Thank you for your prompt reply. I'm sorry I couldn't elaborate on my dataset.

We obtained RNA from three tumor samples with different volume sizes. We want to identify genes whose expression levels change when the tumor grows. The control samples is just a non-tumor samples.

I also know that my dataset is not good for analyzing with deseq2. But is there any way you can recommend it?

So you have 4 samples? I'm sorry, I'm still not certain your experimental design and sample size. How many volumes do you have? Is the volume per tumor sample the same? Are the tumors from different donors? Please post any relevant variables like this:

tumor, volume, donor
1,     15,     1
