SNIRF2BIDS: a GUI-based tool for converting functional near-infrared spectroscopy data to the Brain Imaging Data Structure in R.
Article in Neurophotonics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Significance: Optical imaging with functional near-infrared spectroscopy (fNIRS) often produces complex datasets. The Brain Imaging Data Structure specification (BIDS) has evolved to harmonize fNIRS recordings and to facilitate data sharing, transparency, and reproducibility. However, the conversion of raw fNIRS recordings and associated metadata into BIDS format remains time-consuming and error-prone. Aim: We aim to present SNIRF2BIDS, an R package that streamlines the conversion of fNIRS data to the BIDS format through a graphical user interface. Approach: SNIRF2BIDS automates dataset restructuring, metadata organization, and file naming in accordance with the current BIDS specification. The SNIRF2BIDS-GUI requires R ( Results: We demonstrate the functionality of SNIRF2BIDS in a step-by-step tutorial, guiding users from raw fNIRS recordings to fully BIDS-compliant datasets. Conclusions: SNIRF2BIDS enables standardized organization of fNIRS datasets, thereby reducing manual work and minimizing the risk of human error. It fosters data sharing, thus supporting reproducible workflows and meta-scientific progress in the growing fNIRS research community.
