how can i get p value from miRNA raw readcounts

Question

[husainbioinfos]

...working on lung cancer project and need to find out which genes are deferentially expressed and which are not. for that i a have downloaded miRNA data set from GEO id is GSE110907. And the file i got has to variable gene_id and read counts. from that i have to derive p value from that data/file.

example: input file :

id read_count hsa-miR-100-3p 568 hsa-miR-100-5p 176883 hsa-miR-101-3p 122968 hsa-miR-101-5p 923

output file: id read_count p value hsa-miR-100-3p 568 ? hsa-miR-100-5p 176883 ? hsa-miR-101-3p 122968 ? hsa-miR-101-5p 923 ?

You need to give us more information. A p-value is associated to a certain hypothesis/test. What are you testing here?

What are you interested in knowing using the read counts? If you have multiple samples, you could compute a differential expression analysis where your miRNAs would have a p-value based on the method you used (limma for example.)

i want to perform deferentially expression of genes and want to derive p value.i have file which has miRNA id and read counts. how can i derived p value from miRNA id and read counts ? please explain

It really depend what's you're looking for, and what your data's like. Get an idea of what others have done first and what kind of tools they used, I find that's usually the best approach to figure it out. A good starting point would be to find some existing miRNA DE pipeline.

output file:
