FMRIB Software Library
La FMRIB Software Library (con acronimo: FSL), ch esi può tradurre in italiano FSL è una [[libreria software] che contiene strumenti per l'analisi delle immagini e programmi di statistica per l'analisi dei dati provenienti da immagini di risonanza magnetica funzionale, strutturale e di diffusione del tensore.
Il programma FSL è disponibile sia come file binario pre-compilato che come codice sorgente disponibile sia per computer Apple che per i PC (Linux, Windows Vista e XP). It is freely available for non-commercial use.
Funzioni incorporate in FSL
| Functional MRI | |
|---|---|
| FEAT | Model-based FMRI analysis with straightforward but powerful GUI: data preprocessing (including slice timing correction, MCFLIRT motion correction and PRELUDE+FUGUE EPI unwarping); FILM GLM timeseries analysis with prewhitening; registration to structural and/or standard space images; and fully generalised mixed-effects group analysis using advanced Bayesian techniques. |
| MELODIC | Model-free FMRI analysis using Probabilistic Independent Component Analysis (PICA). MELODIC automatically estimates the number of interesting noise and signal sources in the data and because of the associated "noise model", is able to assign significances ("p-values") to the output spatial maps. |
| FLOBS | Generation of optimal HRF basis functions and Bayesian activation estimation. |
| SMM | Spatial mixture modelling - alternative hypothesis testing using histogram mixture modelling with spatial regularisation of the voxel classification into activation and non-activation. |
| Structural MRI | |
| BET / BET2 | Brain Extraction Tool - segments brain from non-brain in structural and functional data, and models skull and scalp surfaces. |
| SUSAN | Nonlinear noise reduction. |
| FAST | FMRIB's Automated Segmentation Tool - brain segmentation (into different tissue types) and bias field correction. |
| FLIRT | FMRIB's Linear Image Registration Tool - linear inter- and intra-modal registration. |
| FUGUE | Unwarps geometric distortion in EPI images using B0 field maps. |
| SIENA | Structural brain change analysis, for estimating brain atrophy. |
| Diffusion MRI | |
| FDT | FMRIB's Diffusion Toolbox - tools for low-level diffusion parameter reconstruction and probabilistic tractography. |
| TBSS | Tract-Based Spatial Statistics (part of FMRIB's Diffusion Toolbox) - voxelwise analysis of multi-subject diffusion data. |
| Other tools | |
| Inference | Various inference/thresholding tools, including: Randomise (permutation-based inference tool for nonparametric statistical thresholding), cluster (cluster-based thresholding using GRF theory for inference), FDR (false discovery rate inference) and Glm (a GUI for creating model design matrices). |
| FSLView | Interactive display tool for 3D and 4D data. |
| AVWUTILS | Misc utils for converting and processing images. |
