... Hi, I am quite new to methylation data analysis. I am using minfi for illumina 450k data analysis. I would appreciate if someone would answer the following question:  I want to exclude probes with a) detection P-value > 0.01, and b) intensity summarized with < 3 beads. I think this step shou ...

... Thanks for pointing that out! However, I am still looking for answer regarding getting information about number of beads used for summarizing intensities in lumi (analogous to "nbeads <- assayData(RGset)$NBeads in minfi"). best wishes, Krishna ... written 2.4 years ago by krishna3120 1 answer 439 views 1 answer ... Hi, I would like to get number of beads used to summarize intensity in infinium methylation 450k data and remove intensities based on less than 3 beads. I can easily get that information using minfi as follows, nbeads <- assayData(RGset)$NBeads How can do that in lumi? Further, I noticed tha ...

... I have a RNASeq raw count data. I want to generate different versions of the count data with varying level of random noise for a method evaluation. For example, the data with highest level of noise will have fewest differentially expressed genes and vice-versa. I estimated the parameters of the ori ...

... Hi, I understand that voom normalizes the raw count data to log2 cpm data and then estimates the mean-variance relationship from the normalized data. I want to know if there is strong bonding between log2 cpm data and estimation of mean-variance relationship? In other words, will I get sensible re ...
