Hi all,
I want to preface this question by saying that I am a complete noob when it comes to rna seq data analysis and bioinformatics in general. I had some sequencing done by my university's core for 8 samples - 4 conditions with 2 replicates each, and I would like to show with figures the similarities between the four conditions and also the differences. Does anyone have any input on the best way to do this? I am thinking a PCA plot, heat map with all of the genes that are similar, and a heat map with all that are different. Does this sound like a reasonable approach? As far as I am concerned, heat maps would only show the fold change, but I think it would also be informative to show the absolute expression -- I am wondering if maybe not heat plots and instead use simple bar graphs with TPM values? Lastly, I am in a bit of a rush to get some figures made for a manuscript and if you have any recommendations as to how to do this in a quick, cost-effective, user-friendly web-based manner, please let me know. Any help would be much appreciated!
Thank you in advance!
Kellen

are you comfortable with using R?
Nah. Trying to learn now, but not sure I'll have time as my boss wants this out asap.
I guess, then you should follow Lior Pachter's advice on how to write a paper in five minutes highlighting the Maya'an's Lab BioJupies Notebooks. If your experiment doesn't have a very complex experimental design, that may help.
