resolution. |
| Video
Invert |
Selectable for colonies
darker or lighter than substrate. |
| Image Display |
Live or frozen image of sample on screen with optional colour
coding of detected colonies. Point & Click facility to display
parameters of individual colonies. Each separated colony flagged
for count. High resolution pan and zoom window. |
| Detection
Modes |
Automatic, straight &
matrix detection thresholds to overcome variations in agar depth,
opacity and meniscus effects. |
| Measurement Frames |
Circular & rectangular, variable in size & position.
User-drawn irregular shaped frame. Programmable scanning frame
for multi-point or micro-titre plate applications. |
| Image
Processing |
Automatic pre-processing
of the image prior to measurement. Includes sharpen, remove,
separate, erode, dilate & hole fill. |
| Image Editing |
User interaction with the image to exclude or include specific
regions of the sample to avoid interference from debris or labels.
Cut, join, include, exclude, dilate, erode & fill. |
| Filters |
A range of parameters can
be used singly or in Boolean combinations to automatically discriminate
between colonies or debris provided they differ in size, shape
or intensity. They include circularity, axial ratio, area, diameter,
longest dimension and grey level. |
| Colony Size Classification |
Classification by any one of 12 parameters including area,
diameter, intensity. Unlimited number of size tables with up
to 50 classes in any progression. |
| Image
Capture |
Images can be saved and
retrieved as Windows Bitmap files. Auto image save & save
with prompt for each measurement. |
| Macro Builder |
Simple-to-use editor to create measurement macros for specific
tasks. Includes single step replay to assist development. No
programming skills required. |
| Data
Handling |
Colony count/size data
transferred directly to Microsoft Excel workbook. Highly configurable
results tables based on Excel for Study details, dilution factors,
sample codes, count/plate, count/ml, date, time, user, comments
etc.
Measurements can be made either from Sorcerer or Excel. Direct
transfer of data to Microsoft Access and Oracle database tables
Support for third party data processing applications e.g.
spreadsheets, databases, LIMS, Ames data programs. Data transfer
via OLE or Dynamic Link Libraries
Bar code readers can be used to enter sample details |
| Configurations |
Multiple configurations can be saved for different applications
e.g. Ames, TVC, Inhibition zones, Spiral plates, Pour plates |
| Audit
Trails |
Encoded audit trail files
automatically record all system activity including settings,
measurement data and edits. Audit data can also be sent direct
to Oracle databases. |
| Electronic Records & Signatures |
Configurable interface to a database of authorised users.
Optional User Administration program available for use with
Access or Oracle for compliance with the FDA 21 CFR Part 11
Final Rule on Electronic Record & Electronic Signature. |
| User
Levels |
Supervisor, Advanced User
& User levels. |
| User Access Rights |
Supervisors may lock any of the menus, or selected options
within them, to deny Users & Advanced Users access to
particular functions. |
