How to filter output the results

[wfgui]

Hi,
I followed the sample tutorial to analyze the intestinal data and got too many edges.What methods are available to filter the results? Thanks!
This is the code I am running:

#glasso
se.gl.amgut <- spiec.easi(amgut1.filt, method='glasso', lambda.min.ratio=1e-2,
                          nlambda=20, pulsar.params=list(rep.num=50))

#mb
se.mb.amgut <- spiec.easi(amgut1.filt, method='mb', lambda.min.ratio=1e-2,
                          nlambda=20, pulsar.params=list(rep.num=50))

secor  <- as.matrix(cov2cor(getOptCov(se.gl.amgut)))
sebeta <- as.matrix(symBeta(getOptBeta(se.mb.amgut), mode='maxabs'))
