Hi Jose
I am using mac os snow leopard. My commandline is: clean_reads -i Pair01.fastq -o ./clean_reads/output_q20_len50_only3end -p 454 -f fastq -g fastq -qual_threshold 20 -only_3_end True -min_len 50. It only gave me one line error 'segmentation fault' and says python quit unexpectedly in separate window with long error report. A small last part of error report is below:

Then i tried to run clean_reads in ubuntu with same command and gave me error:
IOError: [Errno 2] No such file or directory: 'ual_threshold'
i did specify any file 'ual_threshold'. That was option -qual_threshold' i specified.
any advice..please
