Package 'MatrixEQTL'
... Matrix eQTL can perform separate analysis for local (cis) and distant (trans) eQTLs. For such analysis one has to set the cis-analysis specific parameters pvOutputThreshold.cis > 0, cisDist, snpspos and genepos in the call of Matrix_eQTL_main function. A gene-SNP pair is considered local if the dist ...

In the following, we will address the issue of this slowing down and the related expenditure of energy. We begin by generalizing the results of Hopfield’s kinetic proofreading scheme to more complex ...
