Katrin,

I believe that error message is caused by empty lines of data in the file 
being read by read.table().
What is the last value for "j" printed when you run the code?
What does the file look like at rows j to j+8?

Does your code work if you just submit these lines?

for (i in 0) 
{ j=subjectquantity+6+i*(subjectquantity+7) 
        print (j) 
        results<-read.table(file, header=F, skip=j, nrows=subjectquantity) 

}

Jean
