概覽

Once data is available, users will be notified via email. Two data transfer options are available:

(I) For all users, data could be downloaded via sFTP server.

1. 用戶通過電郵接收 sFTP 用戶名稱及密碼，解壓密碼將於另一封電郵中提供。
2. User downloads data from sFTP server. Instructions can be found 按此.
3. To unzip files, user can use 7zip or winrar .

(II) For HPCF* users only, data could be transferred directly to user-specified HPCF directories.

1. User provides HPCF folder address to the Core.
2. The Core notifies user upon completing data transfer through email.

In compliance with the centre’s data protection scheme, analysed data are compressed and encrypted prior to delivery via sFTP server. Username and password to access sFTP server and password to unzip files are provided in separate email for added security. Data could be unzipped using 7zip or winrar.

Due to limited server hard disk space, data will only be kept for 1 month after delivery. Data will then be removed from our servers without prior notice.

Please ensure that you keep a copy of the data (analysis results and all intermediate files) securely and clearly identified for future reference.

*For more information about HPCF, please visit the HPCF section.

How to Download Files from sFTP Server

概要
This section shows how to transfer files from sFTP Server by setting up and logging into Filezilla client as the preferred FTP client. The downloaded files will be split into multiplex files if the size is larger than 250 GB. Please remember to download the md5sum file in the same folder to verify the integrity of the downloaded file later. Due to the instability of Wi-Fi, Wi-Fi is not recommended to use for the download.

操作步驟

1. Download and install Filezilla client (https://filezilla-project.org). Note: please download the Filezilla client ， NOT the file Filezilla Server.
2. 打開 FileZilla，並把以下的資訊輸入至視窗頂部的 Quickconnect 欄。
   • Host：您獲得的主機地址
   • Username：您獲得的用戶名稱
