Need to update NPMK toolbox

zhangjb39 · May 17, 2023, 11:00am

Last several week, Blackrock update their code for solving timestamp alignment and zero pad for NSx. They make nonzero pad as default. This change is imported, because zero pad can influence the memory usage during importing and sometime may cause error.

Here is their intro about this update:

This merge accounts for changes to software in version 7.6 where continuous data… gets a timestamp on every sample. The changes to the code allow for better parsing for these cases. There is also now a new function `samplealign`. `samplealign` adds or removes dataframes to allow the data to have exactly 30000 samples per second in an NS5/6, 10000 in an NS4, etc. The correction is performed based on the PTP timestamp applied to every dataframe. `openNSx` automatically takes in `samplealign` unless the argument 'noalign' is given to the function. Because the latest firmware and software on Cerebus/Neuroport systems no longer reverts the timestamp to 0 when a recording starts, the 'nozeropad' behavior is now default, and a user must add the argument 'zeropad' to front load the data for alignment.

Thanks @zhangjb39 for the heads-up.

We have updated Brainstorm to use the master branch in NPMK for the Blackrock plugin.

In the past it used the code NPMK Releases, however, it has been more than 2 years releases have not been published, but bugfixes have been addressed in master.

To have the latest NPMK toolbox in Brainstorm:

Update Brainstorm: Update > Update Brainstorm
Update the Blackrock plugin: Plugins > I/O > blackrock > Update (github-master)

Best,
