Read annotations from a file.
.cef, or .set file and makes an mne.Annotations
object.
str
The filename.
float
| ‘auto’The sampling frequency in the file. This parameter is necessary for
*.vmrk, *.amrk, and *.cef files as Annotations are expressed in
seconds and *.vmrk/*.amrk/*.cef files are in samples. For any other
file format, sfreq
is omitted. If set to ‘auto’ then the sfreq
is taken from the respective info file of the same name with according
file extension (*.vhdr/*.ahdr for brainvision; *.dap for Curry 7;
*.cdt.dpa for Curry 8). So data.vmrk/amrk looks for sfreq in
data.vhdr/ahdr, data.cef looks in data.dap and data.cdt.cef looks in
data.cdt.dpa.
str
| None
This parameter is only used in EEGLAB (*.set) and omitted otherwise.
If your *.set file contains non-ascii characters, sometimes reading
it may fail and give rise to error message stating that “buffer is
too small”. uint16_codec
allows to specify what codec (for example:
‘latin1’ or ‘utf-8’) should be used when reading character arrays and
can therefore help you solve this problem.
Annotations
| None
The annotations.
Notes
The annotations stored in a .csv require the onset columns to be timestamps. If you have onsets as floats (in seconds), you should use the .txt extension.
