read.celfiles function reads cel or cel.gz. It may not read Dc6h.04-FWD_251485018671.gpr.txt. Currently your input or one of your inputs is: Dc6h.04-FWD_251485018671.gpr.txt

Then exclude that file. GPR is not CEL format. Please re-check your study design to ensure that you are processing Affymetrix arrays, which come in the CEL format in their raw state.

could you please post output from $ ls raw_data_dir ? gpr is genepix format as I understand.
