[BioC] globaltest procedure

[zhifu sun]

Can somebody share some experience on how to use the
"globlatest" function in "globaltest" package?
Specifically I would like to use it to test the
association between genes in a pathway and survival. I
also have 6 covariates (phenotype variables, the
esprSet object already created with these variables)
for adjustment. After several tries, I could not make
it work (the documentation for the package does not
give details on this kind of analysis) and really
appreciate someone's help.    

Thank you in advance.
