I am doing single cell RNA seq analysis recently and classified my total 76 single cell samples into 3 groups by unsupervised hierarchy clustering analysis. My pseudo-time analysis showed it was pretty good to observe the time-line differentiation process.
Then I did differential expression genes analysis by SCDE package. However, I am confused with selecting differential expressed genes since the output results include 'z' value instead of 'p value' plus 'LogFold change'.
In this case, do I need to, in some way？, transfer the z value to p value? Is z value is the only standard for selecting genes?
I am glad to talk you with more about scRNA-seq!
