From b0d65354584326ea37f4059db7550a5052094c3b Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 13 Apr 2026 01:34:29 +0000 Subject: [PATCH 01/11] Port NDI-matlab analog event types, +Inf clamping, and Neuropixels GLX configs - Add analog event channel types (aep/aen/aimp/aimn) with threshold suffix support to daqsystemstring.py and mfdaq.py, mirroring MATLAB readevents_epochsamples for both live and ingested data paths - Add +Inf clamping to epochtimes2samples and epochtimes2samples_ingested so [-Inf, +Inf] maps to full epoch sample range - Add channeltype2str and parse_analog_event_channeltype static methods to daqsystemstring - Copy 5 new Neuropixels GLX DAQ system configs from NDI-matlab - Update bridge YAMLs with new sync hashes, methods, and decision logs for daqsystemstring (2157c70), mfdaq (9e11fbb), dataset (f485088) - Mark copy_session_to_dataset as deprecated in database_fun bridge (moved to ndi.dataset.copySessionToDataset in MATLAB) https://claude.ai/code/session_01WSbupNz1kLD3RqBMg85ZjJ --- src/ndi/daq/daqsystemstring.py | 57 ++++- src/ndi/daq/mfdaq.py | 208 ++++++++++++++++++ src/ndi/daq/ndi_matlab_python_bridge.yaml | 61 ++++- src/ndi/dataset/ndi_matlab_python_bridge.yaml | 48 +++- .../kjnielsenlab/nielsen_neuropixelsGLX.json | 19 ++ .../kjnielsenlab/nielsen_visnp.json | 18 ++ .../daq_systems/vhlab/vhajbpod_np.json | 19 ++ .../daq_systems/vhlab/vhneuropixels.json | 16 ++ .../daq_systems/vhlab/vhneuropixelsGLX.json | 17 ++ ...ndi_matlab_python_bridge_database_fun.yaml | 6 +- 10 files changed, 460 insertions(+), 9 deletions(-) create mode 100644 src/ndi/ndi_common/daq_systems/kjnielsenlab/nielsen_neuropixelsGLX.json create mode 100644 src/ndi/ndi_common/daq_systems/kjnielsenlab/nielsen_visnp.json create mode 100644 src/ndi/ndi_common/daq_systems/vhlab/vhajbpod_np.json create mode 100644 src/ndi/ndi_common/daq_systems/vhlab/vhneuropixels.json create mode 100644 src/ndi/ndi_common/daq_systems/vhlab/vhneuropixelsGLX.json diff --git a/src/ndi/daq/daqsystemstring.py b/src/ndi/daq/daqsystemstring.py index 23791d6..7b0d3dd 100644 --- a/src/ndi/daq/daqsystemstring.py +++ b/src/ndi/daq/daqsystemstring.py @@ -76,7 +76,16 @@ def parse(cls, devstr: str) -> ndi_daq_daqsystemstring: channeltype = match.group(1) numspec = match.group(2) + # Check for threshold suffix (e.g., '_t2.5' in 'aep1-3_t2.5') + threshold_str = "" + t_idx = numspec.find("_t") + if t_idx != -1: + threshold_str = numspec[t_idx:] + numspec = numspec[:t_idx] + channellist = _parse_channel_numbers(numspec) + if threshold_str: + channeltype = channeltype + threshold_str channels.append((channeltype, channellist)) return cls(devicename=devicename, channels=channels) @@ -96,8 +105,7 @@ def devicestring(self) -> str: if not channellist: parts.append(channeltype) else: - numstr = _format_channel_numbers(channellist) - parts.append(f"{channeltype}{numstr}") + parts.append(ndi_daq_daqsystemstring.channeltype2str(channeltype, channellist)) return f"{self.devicename}:{';'.join(parts)}" @@ -132,6 +140,51 @@ def __str__(self) -> str: def __repr__(self) -> str: return f"ndi_daq_daqsystemstring('{self.devicestring()}')" + @staticmethod + def channeltype2str(ct: str, channellist: list[int]) -> str: + """ + Build a device string segment from a channeltype and channel list. + + Handles threshold suffixes (e.g., ``_t2.5``) by placing the channel + numbers between the base type and the suffix. + + Args: + ct: Channel type string, optionally with threshold suffix + (e.g., ``'aep'`` or ``'aep_t2.5'``) + channellist: List of channel numbers + + Returns: + Device string segment (e.g., ``'aep1-3_t2.5'``) + """ + t_idx = ct.find("_t") + if t_idx != -1: + base = ct[:t_idx] + threshold_str = ct[t_idx:] + return f"{base}{_format_channel_numbers(channellist)}{threshold_str}" + return f"{ct}{_format_channel_numbers(channellist)}" + + @staticmethod + def parse_analog_event_channeltype(ct: str) -> tuple[str, float]: + """ + Extract base type and threshold from a channel type string. + + Given a channel type string like ``'aep_t2.5'``, returns the base + type (``'aep'``) and threshold (``2.5``).

CI doesn't have spikeinterface installed, so the SpikeInterface fallback also fails. Instead of relying on SpikeInterface as fallback, _get_ndr_reader now accepts epochfiles and auto-detects the correct NDR reader from file extensions (.abf -> axon_abf, .rhd -> intan_rhd, etc.) when the stored reader string doesn't match.
