Default problems with downloading files using fasp protocol

Hi all,

I want to use some archival sequence data. I am learning how to use .sra files by following the SRAdb documentation, but I have some problems with downloading .lite.sra files from NCBI ftp site using the fasp protocol as described on page 9 in the SRAdb document. I used the following code in Macintosh Lion.

ascpCMD<-"'/Applications/Aspera Connect.app/Contents/Resources/ascp' -QT -l 300m -i '/Applications/Aspera Connect.app/Contents/Resources/asperaweb_id_dsa.putty'"
sraFiles<-ascpSRA(in_acc = c("SRX000122"),sra_con, ascpCMD, fileType = 'litesra', destDir=getwd())

sraFiles <- ascpSRA( in_acc = c("SRX000122"),sra_con, ascpCMD, fileType = 'litesra', destDir=getwd())

I got the following errors:
Session Stop (Error: Server aborted session: No such file or directory)

Session Stop (Error: Server aborted session: No such file or directory)

Session Stop (Error: Server aborted session: No such file or directory)

Session Stop (Error: Server aborted session: No such file or directory)

Session Stop (Error: Server aborted session: No such file or directory)

Session Stop (Error: Server aborted session: No such file or directory)

Does anybody know what happens? Thank you in advance!

Are you behind a firewall? This could be an issue of the firewall blocking fasp traffic.

Thanks GenoMax. No, my firewall was disabled. Any other thoughts? Thanks!
