Data transfer feature management
Introduction and prerequisites about the feature
Introduction and system configuration
details:
The data transfer feature available in the DECRO range of systems enables data to be transferred from a unit (NANO4) or system (START or ADV) dedicated to acquisition (ACQ) to a local or cloud analysis server (SRV). This feature is available on systems with a lasa software version later than 2.17.
The separation of the two main functions per system: Acquisition and Analysis, allows the user to analyse acquired data while new data is being acquired, without the risk of data loss, and therefore to save time.
Once the data has been transferred to the ANALYSIS SERVER, you can use all the LASA software to explore, analyse and export your data. The SRV can be located directly in the animal facilities (LAN1, Direct connection) or in a room connected to the internal network (LAN 2, Network connection). It is also possible to rent a CLOUD instance, in which case the analysis server is hosted externally and accessible via the Internet. The analysis server has no acquisition capacity, even though it is physically on site.
There are three possible ACQ/SRV communication configurations depending on the location of the analysis server.
However, the principle of pairing the acquisition system with the analysis server and transferring the data remains the same.
Details of the possible configurations are shown below:
> DIRECT/LOCAL: the acquisition unit/system communicates directly with the server via a cable and is used locally in the animal house. (TOP)
> NETWORK: the acquisition unit/system and the analysis server communicate via the internal network and can be placed in two different rooms. (MIDDLE)
> CLOUD: the acquisition unit/system, connected to the internal network, and the analysis server communicate via the Internet. In this case, the analysis server is hosted externally and managed by ETISENSE. (BOTTOM)
For your information, if none of the above configurations (DIRECT, NETWORK or CLOUD) is applicable and communication between the two elements is therefore not possible, the transfer will have to be carried out manually, i.e. by compressing the study or session from the acquisition system, exporting it to a computer and then re-importing it to the analysis server on site or via the Internet to the cloud instance. Article available on exporting and importing data here.
Requirements for networked or internet connection configuration.
To enable the ACQ and the SRV to be networked and send data to each other (NETWORK or CLOUD configuration), you must check with your IT department that the following ports are open.
- Port 443 (HTTPS)
- Port 22 (SSH - rsync)
Even if the previous ports have been opened on the various components, it is possible that certain internal firewalls prevent the two systems from being paired. If this is the case, please contact your IT department. We will be happy to answer any questions you may have.
If the acquisition system communicates with the analysis server via a wired connection (DIRECT), it is not necessary to open these ports. Simply check that the Ethernet cable is placed on the correct ports on both systems to ensure communication between the two elements.
Pairing and data transfer between components
The pairing of the two elements is not initially configured because the URL of the analysis server depends on the configuration of the setup. To do this, once connected to the acquisition system, click on the data transfer button (see below) to access the configuration interface.
A form called ‘Pair to ...’ should appear. It contains the following fields:
To combine the two elements, you need:
In DIRECT OR NETWORK configuration
- Enter the login: use your defined login and password or use the default credentials used to enter the analysis server system for first connection (Default login = adv-srv-00XXX.admin@etisense.com and password = decroAdmin).
- Enter the connection url depending on the setup configuration.
o DIRECT = URL ou IP adresses on the analysis serveur label
o NETWORK = URL of the the analysis serveur given by IT on the internal network
In CLOUD configuration
- Enter the credentials given by ETISENSE by email. Generally, the login will be your first name.surname@etisense.com.
Once validated, this information enables the acquisition system to connect to the analysis server. Once the two elements are linked, this page appears:
If pairing with the SRV fails, the ‘Retry’ button can be used to restart the connection attempt.
If the RETRY button doesn't disappear after several tries, it's because your browser doesn't recognize the analysis server as a “reassuring website” for browser certificate issues. In this case, first log in using a new web tab and the server's connection URL/IP address to authorize the browser to continue to the system, as per the procedure below.
Once the certificate is valid, try the RETRY button again and the DATA TRANSFER page should load on the acquisition unit.
To separate the two elements, simply click on the information button on your storage space:
And click on UNPAIR.
Data transfer view presentation
The ACQ transfer page consists of the following elements:
1. Analysis server expiry date.
Date displayed when a CLOUD interface is rented, otherwise not defined on an on-site system.
2. Remaining storage on the analysis interface.
If space is becoming limited, the value changes to red.
3. Information button.
Displays the previous popup with details of ACQ and SRV storage, the option of visiting the analysis server and the option of unpairing the two elements.
4. Connection status
between ACQ and SRV.
5. Study search bar
6. Refresh button.
If you have just performed an action on a study (Close or data transfer), this refreshes the associated information.
7. Filter list.
Click on a column heading (Name, local size, etc.) to select the display order (ascending or descending).
8. Data transfer action buttons.
These are described in detail in the next section.
There are
three ways of exchanging data between two systems:
If a study is present on both elements but there is a discrepancy in status,
the status of the data on the analysis server takes priority.
For example, if new sessions have been created following an acquisition and then added to the analysis server study with a ‘push’. If one of them has been Detected (post-acquisition feature) in the meantime on the analysis server: the push will not allow the visualisation MERGE (data view button) on the acquisition system. The push is only used to send data, a SYNC must be used in this case.
SYNC
The SYNC action allows you to save and synchronise
- an existing study on the Analysis Server only: Imports the new study or the modifications created on the Analysis Server
into the Acquisition System.
- a study presents on both systems: Merges the version of the study on the Acquisition System (creation of elements or data) and that on the Analysis Server (creation or modification of elements or data).
If a study is present on both elements but there is a discrepancy in status,
the status of the data on the analysis server takes priority.
For example, if new sessions have been created following data acquisition and then transferred and detected only on the analysis server. If a SYNC is performed, these will also be detected with the MERGE display available on the acquisition system.
SYNC Study design
The SYNC STUDY DESIGN action saves and synchronises design data (group, subject and phase).
For example, if the study design has been modified by adding individuals to a group on the analysis server in order to prepare the acquisitions. If a SYNC is performed, the new individuals will also be added to the acquisition system.
How to transfer your data?
To transfer data from one element to another, simply click on the action of your choice.
Data transfer actions are only available on acquisition units/systems.
You have the option of PUSH/SYNC:
1- By using the data transfer view,
which lists the various studies, and select the action at the end of the line for the study whose data is to be transferred.
2-By ticking one or more studies whose data is to be transferred
and selecting the action at the top of the table.
3- By going to the home page of your ACQ system and using the study menu to click on one of the actions to transfer data.
Note that the above buttons are only available if the study is closed on the acquisition system and/or on the analysis server : data transfer is impossible if the study is open or compressed.
Once an action button has been clicked, a loading popup is displayed until communication between ACQ and SRV has been checked and everything is OK for the transfer:
Once the verification is complete, this popup will be displayed.
In the image above, data from several studies with different states will be transferred to illustrate the possible cases. Three lists are displayed:
> The study is present on both systems and the data will be transferred by a SYNC between the ACQ and the SRV
> The study is present only on the ACQ and cannot be SYNC until a PUSH is performed.
> The study whose data has already been transferred and is up to date on the ACQ and SRV
Only the STUDIES TO SYNCHRONIZE state will be performed.
If there is no space on a system for this transfer, a message is displayed and the operation is blocked.
Once the transfer has started, the study has a green background, with a progress bar.
The study
also appears in this state on the ACQ and SRV home pages.
Once the download is complete, you will once again have access to the ACQ and/or SRV data.
