 I downloaded a number of SNP 500K data from GEO to run with CRLMMM.  
The following CEL files specified by GEO as NspI files.  
 > fulFileNames
 [1] "/Users/pcoyne/B_Cluster_DBased/GSE9222/NspI/GSM234158.CEL"
 [2] "/Users/pcoyne/B_Cluster_DBased/GSE9222/NspI/GSM234160.CEL"
 [3] "/Users/pcoyne/B_Cluster_DBased/GSE9222/NspI/GSM234162.CEL"
 > crlmm (fulFileNames,outputDir,verbose=TRUE,
pkgname="pd.mapping250k.nsp")
 chips
 Mapping250K_Nsp      Mendel_Nsp 
               2               1 
 Error in justCRLMMv3(filenames, outdir, batch_size = batch_size,
recalibrate = recalibrate,  : 
   All the CEL files must be of the same type.

 Question 1:  What is Mendel_nsp?  It looks like one of the file is 
Mendel_nsp
 Question 2:  Is this an error that I can by pass with CRLMM and how?
or is it an error that I should report to GEO for fixitng?
 Thanks
