MaSTR™ software’s
unique, easy-to-use interface enables
analysts to create and submit mixture
analysis jobs in minutes. The server-client
configuration provides flexibility
and lowers costs by performing the
analyses on a dedicated computer,
freeing up the analyst’s time and
computer for other tasks.
- Provides a framework for growth:
- MaSTR software easily adapts
future chemistries (Figure 1)
- Upgrade statistical approach
without changing software version
- Utilizes the laboratory’s unique
data set to “train” the software
(Figure 2)
- After validation, lock in models
for casework
Models for the current
statistical approach are preloaded
in MaSTR software; statistical advances
will be included with software updates.
Researchers can easily experiment
with new model variables and submit
to the peer reviewed process for publication
and advancement of forensic probabilistic
analysis.
Interface

Figure 1: Simple,
drop-down menus enable labs to update
panels with new loci, population allele
frequencies, and staff profiles to
the elimination database.
Protocol Set

Figure 2: Protocol data sets
– replicates of single source dilutions
produced following lab SOP enable
MaSTR software to calculate:
- Expected peak height variation
at different RFU (statistical profile).
- Variation from typical degradation
of signal due to lower amount of
amplified product in higher mw loci.
- Allelic stutter percentages.
Models
MaSTR software provides
flexible technology that allows custom
modeling and development.

Figure 3:
The easy-to-use interface provides
tools that allow forensic scientists
to utilize their expertise without
scripting. Researchers can easily
experiment with new model variables
and submit to the peer reviewed process
for publication and advancement of
forensic probabilistic analysis.
