3. Install the decompressed software, for example: sh ibm-aspera-connect-3.11.1.58-linux-g2.12-64.sh

   [path/to/ascp/] -i [path/to/key/file] -P33001 -T -k1 -l100m aspera_download@183.239.175.39:/[path/to/files to download] [path/to/store/downloaded files]
   
   Where:
   [path/to/ascp/] is the execution program of ascp, and its path is: /home/[user]/.aspera/connect/bin/ascp
   
   [path/to/key/file] must be the absolute path of the key file. For example: /home/keys/aspera.openssh

   [path/to/files to download] is the path of the file to be downloaded. Please enter CNSA FTP, copy the data address on the browser you want to download, and delete “https://ftp.cngb.org”.

For example: if you want to download the files under this directory (https://ftp.cngb.org/pub/CNSA/data1/CNP0000007/CNS0000004/CNX0000010/CNR0048164/) on FTP, delete “https://ftp.cngb.org/” in the directory, the rest of the path is: /pub/CNSA/data1/CNP0000007/CNS0000004/CNX0000010/CNR0048164/, which is the [path/to/files to download] that you need to fill in the command line.
   
   [path/to/store/downloaded files] is the path where the downloaded files are stored. For example: /home/[user]/download/
