Siesta DFT Calculation Script Preparation for Nanowire

I'm in need to evaluating the band structure of Si nanowires, and need someone who has experience with the Siesta DFT software. If you think you can replicate the data presented in Figure 2 of (https://arxiv.org/ftp/arxiv/papers/1002/1002.0427.pdf) using Siesta, please let me know. I can run the calculations on my server and provide with the output files to assist you in generating the results.
