Hello all, I have a list of known miRNA's from an experiment in Arabidopsis (example: ath-MIR166a) and I am looking to find out what biochemical pathways they interact with, with KEGG or reactome.db preferably. I have preformed this analysis in humans several times with no issues. If anybody could push me in the right direction, I would appreciate it, especially if it is a solution in R.

Thank you so much for your time and attention to this matter!

Hi JNF3769, I am also working on miRNA's. I have single end fastq files from sequencing centre. I trimmed my fastq files only at the 3'end. The reason for trimming is, generally miRNAs are smaller, so the sequencing machine will sequence the adapter region.



Did you trim any other adapters or primers?

I noticed that in miRBase all mature.fasta file has U base instead of T. But my reads have base T in them.

Did you change the base U to T in mature.fa file in order to do alignment?

I did not need to do alignment or quality control of the sequencing data--it was handed off to me by a legacy researcher and I am more concerned with a qualitative assessment, rather than a quantitative one. I intend to go back and check his work after this to make sure we get the same results, but that is a problem for future me.

Thanks, JNF. Currently, I am looking at the preprocessing step. Would you be able to check with that researcher about the above queries?
