**What it does**
        
Dimensionality reduction of molecular dynamics trajectories. Data can be input as 
tabular or GROMACS XTC files. In addition, data can be projected into a previously 
computed coordinate space by providing precomputed eigenvectors, statistics and 
a correlation/covariance matrix. 

Data can be normalized using the either the covariance or correlation matrix. Data
can also be calculated on a torus, which is useful for periodic data, such as protein
dihedral angles.

.. class:: infomark

**Input**

       - Tabular or XTC file
       - If you want to project data into a previously calculated principal space, you can upload precomputed eigenvectors, statistics and correlation/covariance matrix.

.. class:: infomark

**Output**

       - Projected data (tabular file) with each column representing a principal component
       - Eigenvectors, statistics and covariance/correlation matrix
