Does it really say 'somedirectory/filename.CEL'? Unless that is the 
actual path and filename I find the error rather odd.

Anyway, this error usually means you have a corrupted celfile. The C 
code called by read.affybatch() looks at the dimension for the celfile 
that is reported in the header of the celfile and compares that to the 
actual dimensions of the data. If they are not the same (indicating that 
you are missing part of the file), you get that error.

Best,

Jim
