Description Usage Arguments Details Value Author(s)
Retrieves sQTLs after multiple testing correction and potentially removing svQTLs. The distribution of the P-values and a semi-volcano plot can also be shown.
1 2 |
res.df |
a data.frame, output of 'sqtl.seeker' with the P-values for each gene/SNP test. |
FDR |
the False Discovery Rate to call an association significant. Default is 0.01. |
md.min |
the minimum MD (Maximum Difference) in relative expression desired. Maximum difference in relative expression (MD) gives an idea of the effect size of the association. Default is 0.01. |
out.pdf |
the name of the pdf file to create. If NULL (default), no pdf output will be created. If non-NULL, the distribution of the P-values and a semi-volcano plot (P-value vs MD) will be shown. |
svQTL.removal |
if TRUE (and column 'pv.svQTL' is present in 'res.df') significant sQTL which are also significant svQTLs are not reported. |
FDR.svQTL |
the False Discovery Rate to call a svQTL, that possibly removed from the final set of sQTLs. |
Multiple testing correction is performed using qvalue
package with default parameters.
If svQTL.removal=TRUE
and svQTLs were tested in 'sqtl.seeker', gene/SNPs with
significant svQTL association (after multiple testing correction and similar FDR threshold)
are removed from the final set of significant sQTLs.
a subset of the input data.frame with only significant sQTLs and FDR estimates.
