StarTools uses AIFE.AI for content management and digital footprint. This means that the website content doubles as a printable manual and vice-versa. This content is also available as a smartphone/tablet app, virtual flipbook, virtual reality (VR) experience and more. This content will always be up-to-date with the latest information.
The minimum specifications to run StarTools, increases with the resolution of the dataset you intend to process.
StarTools works on all modern versions of Windows, Linux and macOS.
StarTools is display-device agnostic, but can be configured to display its GUI at a 4x higher resolution to accommodate high-DPI devices and 4K displays.
If StarTools appears to be unstable on your older (up to 2014) macOS device, particularly when using bigger datasets, then this may be due to an underpowered iGPU solution. Particularly the second and third generation Intel-based macOS devices are equipped with minimal GPU acceleration.
If your older or lower-powered GPU or iGPU appears to be unstable on your Windows operating system in StarTools, and you think it may be struggling with any larger datasets you give it, then the issue may be caused an unsuitable Timeout Detection and Recovery (TDR) allowance.
If you find StarTools sometimes crashes under heavy load in demanding modules like SVDecon, this may be due to your Operating System being incorrectly configured to provide enough virtual memory.
Some less reputable virus scanners such as BitDefender, Norton and SpyBot may falsely report StarTools as a Trojan or Potentially Unwanted Program (due to malware that carries a similar name). Despite multiple users going through the lengths of getting StarTools white listed, the same problem pops up every 6 months or so.
StarTools uses all your CPU's cores to speed up processing in situations where it makes sense. As of 1.7, however, StarTools will offload suitable, heavy arithmetic to your GPU as well.
As of version 1.7, StarTools offloads suitable, heavy arithmetic to your system's GPU.
StarTools supports virtually all modern GPUs and iGPUs on all modern Operating Systems.
StarTools is a completely native, self-contained application that does not require any further installation of helper libraries or run-time frameworks.
StarTools is a unique piece of software that keeps track of signal evolution and noise propagation. The data it needs to store and access may grow to many gigabytes. As such StarTools uses your storage memory (hard drive or SSD drive) to store this data. If StarTools is unable to write this data, a message may appear alerting you to this.
