Question: Identify in tandem repeats with Bioconductor

I would like to identify the regions with repeated patterns in a given genome. Let's say that I need to identify [TA]n regions, were 'n' is a variable number of repeats.

I thought in a loop to resolve the problem, however, it will take a long time and will produce redundant regions. Thus, I would like to know if there is a efficient way to analyze that.

G = readDNAStringSet("any.fa")

seqAll <- seq(from =1 , to =1000, by=1) 
ali <- NULL

for(k in 1:length(seqAll)){
nx <- seqAll[k]

patx <- paste(rep("AT",nx), sep="", collapse="")

ali[k] <- vmatchPattern(DNAString(patx), G, max.mismatch=0)

Hi Vinicius,

You might want to check this post for a more efficient approach:
