The following instructions detail the use of SFTP (Secured File Transfer Protocol) to transfer data to and from your Partek® Flow® instance. SFTP offers significant performance and security enhancements over FTP for file transfers. It also enables the use of robust file syncing utilities, e.g. RSYNC, and is compatible with common file transfer programs such as FileZilla and WinSCP.
To transfer files with SFTP, you will need to have your Partek Flow:
Server Name. Example: myname.partek.com
Username. Example: flowloginname
This information should have been e-mailed to you from the Partek licensing team. If you lose this information, contact Partek support and we will resend your authentication key to you.
WinSCP is an open source, free SFTP client for Windows. Its main function is file transfer between a local and a remote computer.
To download WinSCP, visit WinSCP's official site: https://winscp.net/eng/download.php On the WinSCP page you may need to scroll a bit down, to reach the green button Download WinSCP.
Download and install WinSCP on your local computer and then launch the program.
The web address for your instance of Partek Flow has been sent to you by Partek's Licensing team. In this example, the web address is ilukic5i.partek.com.
The file has been sent to you by Partek's licensing team attached to the same email that gave you your URL and username.
WinSCP will ask you to confirm file format conversion
WinSCP will create a file in .ppk format.
Your private key has been saved in .ppk format and added to WinSCP
This will open the Save session as site dialog. You can accept the default name (in this example lukici@ilukic5i.partek.com) or add a custom name. The name that you specify here will appear in the left panel of the Login dialog.
The first time you connect, a warning message will appear, asking you whether you want to connect to an unknown server.
The progress towards establishing a connection will be displayed in a dialog. This process is automatic and you do not need to do anything.
The WinSCP interface includes is split into two panels. The panel on the left shows the directory structure of your local computer and the panel on the right shows the directory structure of your Partek Flow file server.
To transfer a file, just drag and drop the file from one panel to the other. The progress of your transfer will be shown on the screen.
FileZilla is a graphical file transfer tool that runs on Windows, OSX, and Linux. It is great when needing to do bulk transfers as all transfers are added to a queue and processed in the background. It is possible to browse your files on the Partek Flow server while transfers are active. This is also the best solution when you are not on a computer with command line access or you are uncomfortable with command line operations.
We recommend downloading the FileZilla install packages from us. They are also available from download aggregator sites (e.g. CNET, download.com, sourceforge) but these sites have been known to bundle adware and other unwanted software products into the downloads they provide, so avoid them.
Mac OSX:
http://packages.partek.com/bin/filezilla/fz-osx.app.tar.bz2
Windows 32-bit:
http://packages.partek.com/bin/filezilla/fz-win32.exe
Windows 64-bit:
http://packages.partek.com/bin/filezilla/fz-win64.exe
Linux (Please use your distribution's package manager to install Filezilla):
Ubuntu:
$ sudo apt-get update
$ sudo apt-get install filezilla
RedHat, see the following guide:

OpenSuse, see:

After starting FileZilla, click on the Site Manager icon located at the top left corner of the FileZilla window.
Click on the New Site button on the left of the popup dialog.
Type in a name for the connection. Example: “Partek SFTP”.
The connection details to the right need to be changed to reflect the information you received via email. The default settings will NOT work.
Set Host: to your partek server name
Leave Port: blank
Change Protocol: to SFTP - SSH File Transfer Protocol
Change User: to your Partek Flow login name
Change Logon Type: to Key File and select the key file received via email.
When selecting your key file, change the file selection from its default of PPK files to All files. Otherwise you key file will not be visible in the file browser.
After selecting your key file, click the Connect button.
Click the checkbox to always trust this host and click OK. Once connected, you can begin to browse and transfer files. The files and folders to the left are on your computer, the ones on the right are on the Flow server.
When you need to reconnect to your server, run FileZilla and click the down arrow next to the Site Manager icon, then select Partek SFTP.
You will receive a file called id_rsa via email. Download this file, note where you downloaded it to, then use ssh-add to import the key. If you logout or reboot your computer, you will need to re-run the commands below. After key import, you will not be asked a password when transferring files to your Partek Flow server.
$ cd directory/with/key
$ chmod 600 id_rsa
$ eval $(ssh-agent)
$ ssh-add id_rsa
RSYNC is useful when resuming a failed transfer. Instead of re-uploading or downloading what has already been transferred, RSYNC will copy only what it needs.
The command below will sync the folder "local_folder" with the "remote_folder" on Partek's servers. To transfer in the other direction, reverse the last two parameters.
$ rsync -avr --progress ./local_folder/ flowloginname@myname.partek.com:~/remote_folder/
With rsync, don't forget the trailing '/' on directory names.
Before moving the files, we strongly advise you to use FileZilla to explore the directory structure of the Partek server and then create a new directory to transfer the files to.
When you delete files from the Partek Flow server they are gone and can not be recovered.
Please use Partek Flow to delete projects and results. Manually removing data using SFTP could break your server.
Wait until ALL input data for a particular project has been transferred to the Partek Flow server before importing data via Partek Flow. If you try to import samples while the upload is occurring the import job will crash.
