10 | | that can be provided by brain atlases. The first atlases were limited to two-dimentional presentation of structural data. Recently, attempts at creating 3D atlases have been made to offer navigation within non-standard anatomical planes and improve capability of localization of different types of data within the brain volume. |

12 | | The 3D atlases available so far have been created using frameworks which make it difficult for other |
13 | | researchers to replicate the results. To facilitate reproducible |
14 | | research and data sharing in the field we propose a SVG-based Common |
15 | | Atlas Format (CAF) to store 2D atlas delineations or other compatible data |
16 | | and ''3D Brain Atlas Reconstructor'' (3dBAR), software dedicated to automated |
17 | | reconstruction of three-dimensional brain structures from 2D |
18 | | atlas data. The basic functionality is provided by 1) a set of parsers |
19 | | which translate various atlases from a number of formats into the CAF, |
20 | | and 2) a module generating 3D models from CAF datasets. |

22 | | This methodology allows for the generation of 3D models in a |
23 | | reproducible and configurable manner. The users of the software may |
24 | | also track and review the whole reconstruction process in order to |
25 | | find and correct errors. |
26 | | Our workflow allows for manual corrections to be made when |
27 | | automatic reconstruction is not sufficient. |
| 28 | The whole reconstruction process is reproducible and can easily be |
| 29 | configured, tracked and reviewed, which facilitates fixing |
| 30 | errors. Manual corrections can be made when automatic reconstruction |
| 31 | is not sufficient. The software was designed to simplify |
| 32 | interoperability with other neuroinformatics tools by using open file |
| 33 | formats. The content can easily be exchanged at any stage of data |
| 34 | processing. The framework allows for the addition of new public or |
| 35 | proprietary content. |
