Hi Nate, I loaded the file named s_6_1_sequence.txt.gz (Illumni file) under the login name abdul.banday@uconn.edu<mailto:abdul.banday@uconn.edu> as FTP.<ftp://ftp.R> Whenever I am trying to load it as history so that I can run it for analysis, the file upload is showing error and massage comes as data cannot be uncompressed. I have been trying to contact you guys from five days now. In one email you told me as soon as you have ftp transfer let me know. Could you check my file and see what is the problem. Thanking in anticipation. Postdoc at Uconn Rouf Banday
