# montage and data chunks
|
|
|
|
You can export data using a montage of your choice by using --montage_file option.
|
|
|
|
The exporting process will use the montage and export channels accordingly.
|
|
|
|
|
|
|
|
You can also export only one or several chunks of the original data by using markers.
|
|
|
|
If you have previously marked your data for export with a dedicated marker, you can specify the --user_markers opion.
|
|
|
|
This option should be used with a marker file using --marker_file option or with the default marker file associated with the data file (if you add the marker in THAT file).

# Usage
|
|
|
|
convert MEG file to ADES:
|
|
|
|
~~~~bash
|
|
|
|
anywave --input_file D:\data\1\cf,rDC --output_file meg_data --output_dir d:\converted
|
|
|
|
~~~~
|
|
|
|
Creates meg_data.ades, meg_data.dat and meg_data.mrk files in d:\converted.
|
|
|
|
|
|
|
|
convert EEG data to VHDR:
|
|
|
|
~~~~bash
|
|
|
|
anywave --input_file D:\data\eeg\patient1.cnt --output_file patient1 --output_dir d:\converted --output_writer "brainvision analyser format"
|
|
|
|
~~~~
|
|
|
|
Files patient1.vhdr patient1.eeg and patient1.vmrk will be created in d:\converted.
|
|
|
|
|
|
|
|
convert EEG and filter data:
|
|
|
|
~~~~bash
|
|
|
|
anywave --input_file D:\data\eeg\patient1.cnt --output_file patient1 --output_dir d:\converted --hp 1 --lp 120
|
|
|
|
~~~~
|
|
|
|
Files patient1.ades patient1.dat patient1.mrk will be created in d:\converted.
|
|
|
|
Data will be filtered in band (1-120Hz)
|
|
|
|
|
|
|
|
convert eeg and reduce sampling rate:
|
|
|
|
~~~~bash
|
|
|
|
anywave --input_file D:\data\eeg\patient1.cnt --output_file patient1 --output_dir d:\converted --decimate_factor 2
|
|
|
|
~~~~
|
|
|
|
If we consider patient1.cnt file to contain 1024Hz data, the output patient1.ades file will contain 512Hz data. |
