Overview

About

Maintained by Zhengjia WangCRAN page ↗GitHub ↗Website ↗Issues ↗

Loads 'Blackrock' https://blackrockneurotech.com neural signal data files into the memory, provides utility tools to extract the data into common formats such as plain-text 'tsv' and 'HDF5'.

Changes in 0.1.0

HDF5 is now read and written directly by readNSx, linking against hdf5lib for a static build of the HDF5 library. This removes the dependency on hdf5r and the HDF5 system requirement; no system HDF5 installation is needed on any platform
Removed the hdf5r code path and the plain-R .ralt fallback store; there is now a single storage implementation. The layout on disk is unchanged, so files exported by earlier versions read back unchanged and files written now stay readable by hdf5r, h5py, and command-line HDF5 tools
Channel datasets are no longer capped at 2^31 samples: dimensions and offsets are carried as doubles all the way into HDF5
Reading a contiguous range from a channel now reads only that range instead of the whole dataset

Show all changes in 0.1.0Hide the rest of the changes in 0.1.0

h5_valid(file, "w") no longer truncates the file it is asked about
Added complex support, stored as the H5T_COMPOUND {"r", "i"} of doubles that numpy and h5py use for complex128. Complex datasets written elsewhere are read back as complex whatever their member names, including the {"Real", "Imaginary"} layout hdf5r uses and HDF5 2.0 native complex
Strings are now written as UTF-8 rather than being labeled ASCII regardless of content, so non-ASCII text survives. For plain ASCII the stored bytes are unchanged. Strings are read using whatever character set the file declares, so files written by earlier versions are unaffected
NA_character_ is now stored as an HDF5 NULL and read back as NA. Previously it became the literal text "NA", which no reader could tell apart from a genuine "NA" string
NA in integer, double and logical vectors round-trips exactly, matching what hdf5r stores bit for bit

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)

install.packages("readNSx", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("dipterix/readNSx")

Development version from dipterix/readNSx. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-readnsx

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-readNSx

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager
