I want to convert CEL format data using APT(Affymetrix Power Tool) as per its Affymetrix-PennCNV protocol but the APT command line is not letting me process the data with the command

apt-probeset-genotype -c lib/GenomeWideSNP_6.cdf -a birdseed --read-models-birdseed lib/GenomeWideSNP_6.birdseed.models --special-snps lib/GenomeWideSNP_6.specialSNPs --out-dir apt --cel-files listfile.txt (as directed by Affymetrix-PennCNV protocol on PennCNV website)

The following error shows: Wrong number of cells in channel 0 Expecting: 6892960 and <my file=""> has 1416100
