When using champ.norm to process the data, the following error occurred
Here is the error message that I get:
myNorm <- champ.norm(beta=myLoad$beta,arraytype="450K",cores=5
[===========================]
<h2>[>>>>> ChAMP.NORM START <<<<<<]</h2>champ.norm Results will be saved in ./CHAMP_Normalization/ [ SWAN method call for BOTH rgSet and mset input, FunctionalNormalization call for rgset only , while PBC and BMIQ only needs beta value. Please set parameter correctly. ]
<< Normalizing data with BMIQ Method >>
Note that,BMIQ function may fail for bad quality samples (Samples did not even show beta distribution).
5 cores will be used to do parallel BMIQ computing.
Error in champ.BMIQ(beta[, x], design.v, sampleID = colnames(beta)[x], :
task 1 failed - "could not find function "blc""
thanks,
