PETROG runs on the following Microsoft platforms : Windows 10 and Windows 7 (32 and 64 bit).
It should still run on Windows XP™ SP3, Windows Vista™ or Windows 8/8.1™ (32 and 64 bit) platforms, but they are no longer supported or tested.
No other operating systems are supported. It is important to ensure that the camera you select to use with PETROG is also supported on that platform with the necessary drivers.
Note that on Windows 10 PETROG/PetrogLite run as desktop applications, not the Metropolitan interface.
Please ensure that your computer also meets the system requirements of your selection of camera. Some cameras require fast CPUs, large amounts of memory and specific operating system versions to function.
We would recommend 8Gb of RAM is recommended for PCs running PETROG, and 4Gb for PetrogLite.
Due to the large number of images involved, a lot of storage space is required for PCs running PETROG. We recommend at least 200GB of hard disk space for the storage of images, and further storage such as a DVD writer drive for the archival of image files.
PETROG is supplied with a digitally controlled high-precision Stepping Stage, to replace the discontinued Prior Scientific Instruments / Hacker Instruments electro-mechanical stepping stage (model J0415C). The digital Stepping Stage requires a USB 2.0 port for connection to the controlling computer.
The user interface incorporates video images from a colour microscope-mounted video camera. CVS normally supplies PixeLINK cameras or the Leica DFC 290 digital camera but other cameras, including others in the DFC range are supported. The camera should be a high resolution camera, suitable for collecting images that will later be required for hardcopy production.
All cameras have to be attached to a polarising photomicroscope using a C-mount adapter. The specific model of adapter used is dependent on the microscope. Supported digital cameras require specific connections usually USB 2.0 or IEEE 1394 ("Firewire").
Ensure that the selected camera is supported on the appropriate Microsoft Windows™ platform.
PETROG is no longer supplied for use with analogue video cameras, but we continue to support installed versions.
If your camera requires a IEEE 1394 "Firewire" interface you should check carefully with the manufacturer to see if your camera requires a 4-pin or 6-pin connection. A 6-pin connection provides a power supply and some cameras have a requirement for the power supply. You can add power supply to a 4-pin connection by using a Firewire hub which has it's own power supply. Note that Sony may refer to the 4-pin Firewire connection as iLink.
There are also two speeds of connection Firewire 400 and Firewire 800. The 800 pin connection is a different type of connector. If a Firewire 800 connection is required, then attempting to use Firewire 400 will result in the system not functioning correctly, the malfunction manifests itself differently depending on the camera make and model.
