Matlab h5read errors

Not sure why I am getting this error with h5read, I'm trying to read the first 5000 samples for the first 100 channels

pathFileNetwork = '/Desktop/network_data_full.raw.h5'; 
networkDataInfo = h5info(pathFileNetwork);
rawpath = '/recordings/rec0000/well000/groups/routed';

h5disp(pathFileNetwork,[rawpath '/raw'])

HDF5 network_data_full.raw.h5

Dataset 'raw'

Size: 1199800x1007

MaxSize: Infx1007

Datatype: H5T_STD_U16LE (uint16)

ChunkSize: 200x1007

Filters: unrecognized filter (mxw-data), deflate(0)

FillValue: 0

networkRawData = h5read(pathFileNetwork,[rawpath '/raw'],[1 1],[5000 100]); 

Error using h5readc

The HDF5 library encountered an error and produced the following stack trace information:

H5PL__find can't open directory

H5PL_load search in paths failed

H5Z_pipeline required filter 'mxw-data' is not registered

H5D__chunk_lock data pipeline read failed

H5D__chunk_read unable to read raw data chunk

H5D__read can't read data

H5Dread can't read data

Error in h5read (line 58)

[data,var_class] = h5readc(Filename,Dataset,start,count,stride);

solved!

downloaded a Decompression Library to the desktop

opened terminal

touch ~/.zshrc
open ~/.zshrc

add the following line of text and save

export HDF5_PLUGIN_PATH=/Users/maxone/Desktop:$HDF5_PLUGIN_PATH 

back in terminal

/Applications/MATLAB_R2018a.app
./matlab

run code in matlab

adjust mac security settings to "Allow Anyway"

I hope this helps anyone having a similar issue!

Hey Jon, I am having the same issue actually. Thank you for your post! Which decompression library are you using?

Hi Pierre,

This is the library I used:
