Hi All,

I am using normalize.loess( ) to normalize the CodeLink arrays using:

norm <- normalize.loess(raw, epsilon=10^-3, log.it=FALSE, span=0.4, maxit=2)

At the end, it throws up the following:

Warning message:
No convergence after 2 iterations.
 in: normalize.loess(ch, epsilon = 10^-3, log.it = FALSE, span = 0.4,

I increased the number of iteration to 5 but still getting the same warning
message.  Is it safe to ignore this warning message? If not, what should I
need to do for a normal exit after convergence?
