Jan, Resampling is a good idea to test the robustness of clustering and classification. You may paste and run the following R code in R to do resampling: #...

Cheng, Just out of curiosity, in this manul, PM only model is kind of ignored. I havn't really follow on this lately, but does this mean something or just I am...
Thanks for the URL to the PM only analysis at http://biosun1.harvard.edu/complab/dchip/pm%20only.htm . The text there says "When a cross-hybridizing non-target...

Wen, What do you see at “PM/MM data view”? Does the animation show different intensities values for a spike-in gene in different samples? Could you export...
Hi Cheng, I can see the difference in PM/MM view (see the screenshot in the attached file) There are two attached files: One is exported expression values...
Hi, Wen: I'm not sure why you only used the data from 4 chips (as shown in the picture in your word file)? There are way more chips on the download center....
Tao, The a-d chips do have various concentrations for the spike-in genes. For example, 1708_at has concentration 1024, 0, 0.25 and 0.5. Wen, I can reproduce...

Dear Cheng, I have a question regarding replicates, as far as I understood, I can indicate the samples as replicates only in case when they are experimental...
Mirzo, In your case you don't need to pool replicates (see below for more details); if you have two replicates for each of the 6 samples you may pool...
Dear Dr Li and others, I am sorry to bother you with this, but I would really appreciate an answer. Is it better for me to go from 1.1 version to 1.2 version...
