How many .cel files can I analyze at one time?

This greatly depends on the normalization method selected.

  • Median normalization — you can anticipate the ability to do an arbitrarily large number of .cel files.
  • Quantile normalization - limited to around 9 .cel files (may vary depending on your particular hardware).
  • Sketch normalization — default normalization method which provides quantile-like normalization on an arbitrarily large number of .cel files.
  • The overall current limit on the preferred hardware specification appears to be about 130 .cel files and is associated with the signal summarization step (exact-probe-summarize).
