[BioC] Regarding Phenodata and MAIME data

[James MacDonald]

You don't need either phenoData or MIAME information in order to analyze
your data. These things are simply useful information that you *could*
use for analysis (in the case of phenoData), or for data reporting (in
the case of MIAME). Neither is strictly necessary. In fact, I personally
have yet to use either.

HTH,

Jim

Dear Bioconductor,

I have CEL files ONLY, no other files I have. 
how should I read phenodata or MAIME information from there. Do i need
Phenodata.txt/MAIME.txt for
Microarray analysis or make one or where can i get it? 

Presently I am doing:

my.filenames <- list.files(,"CEL");
f <- as.matrix(my.filenames);
n <- nrow(f); # to get number of files in my list make use for furthere
analysis

my.pheno <- read.phenoData(sampleNames = my.filenames);
abatch <- ReadAffy(filenames = my.filenames,phenoData = my.pheno);



I am student at University of New Haven,CT and I am doing Microarray
analysis  by myself.

 
I highly appreciate your reply,

Saurin Jani
