Hi all, I am trying to read a file called "chr1.gen" that contains imputation posterior probabilities (3 values per SNP) and SNP names in the second column, and I am trying to use the snpStats function "read.impute", but when I try to read the whole file: x=read.impute("chr1.gen")) I get the following error message: Error in read.impute("chr.gen") : input field exceeds buffer length However the data seems to load when I set a limit for the number of SNPs: x=read.impute("chr1.gen",nsnp=200) Does anyone know what this error means? Is it expecting maybe a subset of the file, or is this an R issue? I could not find any examples of this on the web, so if you have encountered this error before please let me know. Thank you -fra [[alternative HTML version deleted]]

i was able to trigger this error by supplying a snp id with more than 126 characters (BUFFERSIZE of the read_uncertain.c source). check for a record that has a very long string, perhaps because whitespace was accidentally eliminated in generating the impute2 output.

Hi Vincent, Thank you very much for your reply. I don't see anything wrong with the maximum line I can load (N=363), but it is hard to tell if there is an extra space since it is a huge dataset I'll look through it better, hopefully I'll find something.
