New spatial calibration techniques    
Distance measurement tools    
Multiple color channel format handling    
Create color composite images    
Sharpen, emboss and starfield subtraction tools    
Local zoom tool provides a magnified area of your image in a second window    
Synchronized pan and zoom tool lets you simultaneously explore multiple images    
Rotation of image for best lane/band tracking accuracy
Macro recording and programming (basic-like)
Macro player to view Gel-Pro macros    
Intensity and spatial calibration
Non-destructive annotation overlay  
3D surface plot to aid data interpretation  
Full support for acquisition of sequences and extraction of frames for analysis  
Undo buffer  
Recovery of analysis progress from inadvertent computer power loss  
Support for the GLP/CRF 21 Part 11 Compliance using audit trail and image/file signature  
Operator identification management based on NT log-in    
As part of the annotation toolbar, fields  appear for date, time, and filename  
Tooltips are enabled to give information known about lanes, bands, dot/blot spots or area density spots  
Automatic lane recognition
Recognizes and tracks curved lanes
Editable lane definition
Lane annotation and ID
Option for non-uniform lane width; individual lanes may be different widths  
Active lane in profile is outlined boldly both on the image and the profile which aids the user when many lanes are displayed  
Ability to define variable well origin for 1D analysis  
Automatic band recognition
Add/delete bands on image or profile
Display bands by extent or crosshair indication
Band annotation
Interactive band height sensitivity to aid in proper automatic band finding  
Define band pattern (grimace) to achieve better band resolution for closely-spaced, distorted bands  
ID by band position within lane or by rows of equal Rf or MW  
Band extents may be edited via handles on the profile
Band extents may be edited via handles on the image overlay  
User may select position for band labels for optimum clarity  
Ability to perform a fourth order polynomial best fit warping for user selected bands that are interpolated  between defined bands) through the rest of the lane  
Lane Profile      
Show single or multiple profiles
Bands may be indicated by peak position or center of mass
Lane bitmap may be displayed under the profile to aid interpretation  
Bands may be indicated by brackets, dotted lines or cross-hatching  
Band indicators are arrows to pinpoint band position  
X and Z scale zooming for close examination  
Easy cycling and selection of the lanes via the profile dialog display  
Flat offset
Extract from background
Filtered profile
Rolling disk  
Option to subtract background for profile display
Option to display image with background subtracted to let the user visualize whether a correct background method has been applied  
Interactive feedback of results as the methods and parameters are changed to optimize results  
Amount may be determined by the area in the profile under the entire profile or only the area within the bands  
Assign quantitation relative to amount loaded on the lane
Ratio to single band, band row or lane
Build calibration curve fit: first - third order polynomial and Lagrange
Multiple amount calibration curves can be defined and used on a single image  
Results Table      
Show MW, amounts or both  
Show amounts, relative amounts, %, IOD or Max OD  
When bands, lanes or rows are selected, the corresponding elements on the image are outlined boldly to aid user interpretation  
The row band graph shows a bar chart of the amounts within a row across each lane  
Presence/absence may be indicated matched to lane 1 via 0, 1, -1 assignment for easy typing  
Molecular Weight      
Slant correction to correct gel warping and uneven band migration
Multiple MW standard lanes with auto-slant correction
Hyperbolic cosecant curve fitting produces more accurate MW calculation for small DNA fragments (under 1,000 base pairs) run in polyacrylamide  
Polynomial slant fit lines may be specified to follow uneven migration more closely and give more accurate results  
Identify regular or irregular layouts of regular spots
Quantitate by ratio methods
Quantitate by calibration curve methods
Three background determination options
Auto or manual thresholding
Choose elliptical or rectangular spot designation
Replicate sampling data analysis
User may ask to have missing spots filled in automatically for a regular array when all dots are not found  
An area filter tolerance may be specified to sort out actual spots from background contamination  
Area Density      
Free form or auto-trace definition of spots of interest  
Extensive table of measurements and measurement statistics
