Integrated Morphometrics Package (IMP) Suite

In cooperation with Prof. Dr. H. David Sheets, we are happy to announce that we can now provide the full Integrated Morphometrics Package (IMP) Suite here. Prof. H. David Sheets is one of the authors of the well-known book Geometric Morphometrics for Biologists: A Primer by Miriam L. Zeldith, Donald L. Swiderski, H. David Sheets and William L. Fink, which also references the IMP software suite. He is now unable to maintain support for this software and has thus taken down the website on which IMP was previously available. Hence, we have taken it upon us to fill in the distribution role and provide continued access to both current and legacy versions of the IMP software suite. However, all software below will have to be considered as Abandonware, meaning that except for the comment section here as well as potential groups present at other social media, there will be no more support available for this software.

What is IMP?

IMP is a set of compiled software tools with graphic user interfaces that carry out a wide variety of tasks related to the display and analysis of landmark-based geometric morphometric data. IMP can read files in the TPS file format used by F. James Rohlf’s TPS series software. All of the IMP programs use the same file format, and are meant to work in conjunction with one another. Each program in the IMP series is meant to carry out a limited number of specific tasks, so that a complete analysis of your data will require the use of more than one IMP program. Since they share a common file format that also loads easily into other software such as R, SPSS and Excel, progressing through a series of different programs to carry out the analysis is not as daunting as it might seem initially. Each program in the series is meant to be easy to use, and the controls of the various programs operate in similar ways. This is meant to ease the learning curve for the software, and allows for a lot of flexibility in how the software operates. A few programs for 3D morphometric data are also available, as are programs to use semi-landmarks along curves. A more detailed description of the software can be found in the IMP manual.

The most current version of the IMP suite is IMP 8, which runs under Mac OSX 10.7, 10.8 and under Windows 7, 8, 10. IMP 8 was compiled using Matlab 8.2, when you download and run these programs, they will download the Matlab drivers needed to run the programs from the Mathworks Corporation, and install the dynamic link libraries needed to run IMP 8. In IMP8, many previously independent programs have been bundled into a more limited number of packages. CoordGen 8 for example can call TMorphGen, SemiLand, MatchMaker, BigFix and VisProto Editor. CoordGen 8 doesn’t look much different than earlier versions, and isn’t any harder to use, but it now serves as a starting point for the other programs. This should simplify using IMP programs by reducing the sheer number of them. These programs will not run within the Matlab environment, they are compiled versions of the Matlab functions. IMP programs will tend to start slowly, due to the need to load a lot of library files, be a bit patient. The bundling of multiple tools into a single package helps to reduce this problem slightly when you are using a number of different tools.

How to cite IMP?

If you are using IMP in your research, please cite it as follows:
Here, we use CoordGen 8 as an example, please replace this with the respective software that you used. Moreover, the years should be different dependent on which IMP version you used. For IMP 8, cite the year 2014, for IMP 7, the year 2010. The most up-to-date IMP 6 versions should be cited with the year 2007 and the IMP 6 versions frozen at the time the 2003 book was released, the year 2003.

Are there any up-to-date alternatives to IMP?

In case you would like to consider other software, the GeoMorph package for R is a suitable alternative. According to the accompanying paper, it provides routines for all stages of landmark‐based geometric morphometric analyses in 2D and 3D. A Quick Guide for GeoMorph is also available.
