PrOCoil - Predicting the Oligomerization of Coiled Coil Proteins
We have developed an SVM-based classification method for predicting whether a
given coiled coil sequence is a trimer or dimer (assuming that it is one of both).
This method also allows for a deep analysis of the sequence which residues are
mainly responsible for the outcome. The software is available as an R package
and as a simple-to-use Web application
. All data used for evaluating the computational approach
and for training the final models are available for download
Installation of R package procoil via Bioconductor
The R package procoil
is available from
The current version of the package is 1.6.0 and has been released as part of
on April 2, 2012. To install procoil
, follow the simple standard procedure
for installing Bioconductor packages, i.e. enter the following into your R session:
Please note that Bioconductor 2.10 requires an R version ≥ 2.15.
Manual installation on older R versions
We recommend potential users to use the latest version of R and Bioconductor and to follow the installation
procedure described above. The R package procoil
1.6.0, however, also works with older R versions.
If you have an R version ≥ 2.10.1, you can still use procoil
1.6.0, but you have to download and install
the package manually:
- Download the suitable package file from the Bioconductor 2.10 procoil page.
- Follow the standard procedure for installing the package file on your system.
To use the package, enter "library(procoil)
" in your R session.
To get a basic introduction, enter "help(procoil)
" or open the
user manual by entering "vignette("procoil")
