== General division ==
 +
AS the TISEAN package consists of 74 programs it needs to be divided into subparts that can be tackled separately and create a entity in-and-of-themselves. I chose to work along the lines of how the documentation introduces programs in its package. This representation can be found [http://www.mpipks-dresden.mpg.de/~tisean/Tisean_3.0.1/docs/chaospaper/TiseanHTML.html| here]. I will discuss in which order I would like to port various topics in the documentation and where my work currently stands.
 +
==== Nonlinear noise reduction ====
 +
This is the first topic I chose. It is because it contains programs from all three categories. It is also relatively small -- it contains 3 programs: project, lazy, ghkss. I have chosen to further implement addnoise and henon, to demonstrate how project and ghkss work. Thus this topic contains programs from each category:
 +
* Re-implementable in mfile (henon)
 +
* Linkable to FORTRAN (project, addnoise, lazy)
 +
* Linkable to c (ghkss)
 +
I have already started work on this stage. My progress can be viewed at [https://bitbucket.org/josiah425/tisean| https://bitbucket.org/josiah425/tisean]. So far I have implemented addnoise, project and re-implemented henon as an mfile. As most work on this topic has been completed I estimate that finishing it up around 2 days -- I estimate 1 day per function (that includes documentation and testing).
 +
==== Phase space representation ====
 +
This is the next topic that needs to be implemented. This is because it contains programs (especially 'delay') that are used to visualize data. Whenever an example is given in the package the resulting data is routed through 'delay' before it is plotted. Apart from delay it also contains other functions that can divided into the following categories:
 +
* Linkable to FORTRAN (autocorr, pc)
 +
* Linkable to c (delay, corr, mutual, false_nearest, pca)
 +
Assuming around a day for each function (with testing and documenting the usage) I assume this stage will take a little over a week.

Porting of the TISEAN package has a couple parts. First part is making the FORTRAN and c programs accessible to Octave. Second part would be creating makefiles and putting all that code in a neat package.
