Error in picksoftThreshold() function of wgcna package for microarray data

Question

[nidhivatsa007]

I'm trying to construct and analyze a network with microarray expression profiles of some mouse genes but for module detection there is following error while analysing softThreshold powers :

pickSoftThreshold(multiExpr[[1]]$data)

Error in summary(lm1)$coefficients[2, 1] : subscript out of bounds

I'm not able to understand and rectify this error. Plzz help

I would suggest that you check whether multiExpr[[1]]$data a) exists and b) is what you think it is

[nidhivatsa007]

I've checked it.....It's correct.......still the problem continues

[WouterDeCoster]

Could you give an overview of the code you used to get to that point? That way we can detect whether something went wrong in earlier steps...
