ProtoLife has unique, cost-efficient, pay-as-you-go approach to
pricing. We do not require costly ongoing subscriptions, and instead
enable users to pay for use of PDT generation by generation.
Pricing below is cited in terms of PDT credits, purchased at
after registering as a user, and logging in). Currently PDT Credits
may be purchased at $1 per credit.
Normal pricing of PDT is dynamic, in that it depends on the complexity
of your problem, which scales with the size of your experimental
space definition (ESD). Some details of dynamic pricing are given
below. The basic price starts out at less than 100 PDT credits per
generation for relatively simple ESD's. An example ESD costing about
100 PDT credits per generation has five experimental parameters with
five values each.
Our web interface hits a maximal experimental complexity when ESD's
reach 20 parameters with 20 values each. PDT can be configured to
handle larger ESD's; please contact PDT Sales to
negotiate pricing for such special projects.
If you sign up with a valid promotion code, you will receive 1000 free
PDT Credits for evaluation purposes. Please contact PDT Sales if you did not
receive a promotion code, or if you need additional credits to
complete your evaluation.
After the free promotional PDT credits are exhausted, users may pay to
obtain more credits, using our credit card interface.
Substantial discounts are available for purchasing PDT credits in bulk. Please inquire.
Substantial discounts are available for academic research, especially
student projects. Please inquire. For
large academic projects, we expect expenses for PDT to become
incorporated into grant budgets.
Dynamic pricing details
Usage of PDT is priced to reflect usage of computational resources,
both CPU and memory usage. The actual dependence on computational
resources used by an experiment determined by an experimental space
definition (ESD) is nonlinear, but our pricing algorithm implements a
linear approximation to these nonlinearities.
In the graphs below, we consider a range of ESD's for Factorial
experiments, to illustrate variations in price per generation. The
graphs illustrate price dependence with respect to the number of
experimental parameters, and to the number of values each parameter
has. The price also varies with the number of experiments performed
per generation, but this variation is weaker, and not illustrated.
In all examples, we price an ESD that has a certain number of
parameters, with a fixed number of values per parameter, the same
number of values for all parameters. Note that in typical real-use
cases, an ESD will have different numbers of values for different
parameters; this would be reflected in the pricing algorithm, though
it is not explored in the graphs below.
The following figure illustrates how price increases as a function of
the number of parameters, for a range of number of values per
parameter, assuming a population size of 30 experiments per
generation. Of all components of the ESD, the number of parameters
has the strongest influence on price.
The next strongest influence on price comes from variations in the
number of values allowed for each parameter. This dependence is
illustrated in the following graph, for a range of different numbers
The price is also affected even more weakly by population size; this effect is not illustrated here.
When you enter your ESD into the web interface, the price per
generation (in PDT Credits) will appear in the left sidebar. This
amount will be debited from your account each generation. Proceeding
to experimental design of the first generation will indicate your
acceptance of this price.
For experimental space definitions that lie outside the ranges
reported here, ProtoLife experts may be able to create a custom
configuration. Please contact PDT Sales for
