Table V. Comparison of the PANorama and P-TRAP software platforms.
Features that are not supported in PANorama or P-TRAP version 20130213220 are labeled with (NS).
Parameter | Feature | PANorama | P-TRAP |
---|---|---|---|
Software implementation | Image acquisition | Built directly into the pipeline with skeleton preview | NS |
Skeletonization | Based on exact morphological erosions of a shape | Axes connected with straight-line segments | |
Skeletonization | Potential for future software releases to target differently shaped image objects | Generates skeletons for branching structures only | |
Axis definition | Internode/awn filtering built directly into skeleton calculation with adjustable parameters | Internodes and awns must be manually edited using a GUI | |
Axis definition | User divides the primary axis three times | User divides the primary axis two times | |
Axis definition | Skeleton points are selected on top of a _skel.jpg image, generating an accessory file | Points selected within a skeleton graph and require manual editing of the skeleton | |
Software execution | Linear pipeline controlled with scripts | Self-contained GUI | |
Compatibility | Linux | Windows, Mac OSX, and Linux | |
Beta testing | Image number | More than 2,600 images in this study | 26 images |
Genetic mapping | QTL mapping using 154 RILs in rice | NS | |
Phenotyping differences | Primary axis internodes | Length of individual rachis internodes | Mean internode length only |
Primary axis thickness | Mean and maximum thickness measures | Mean thickness only | |
Branches per internode | Calculated at every internode (mean and maximum) | NS | |
Exsertion phenotypes | Length and thickness | NS | |
Secondary/tertiary axes | NS | Branch length, count, and number of internodes | |
Spikelet traits | NS | Count, length, and shape |
