Extract(fname=None, silent=True, **kw)

source code

Creates a new data file from (parts of) the currently showing data. To extract some other selection of data (non-graphically defined), build a list of qubx.data_types.SourceSeg and use qubx.data_types.Save.

Keyword options:

* fname: overrides path_expr with a specific path/to/file.ext * silent (=True): doesn't graphically prompt the user for options * source - SOURCE_DATASOURCE, SOURCE_LIST, or SOURCE_OTHER * other_seg - OTHER_SEG_ALL, OTHER_SEG_ONSCREEN, or OTHER_SEG_GROUP * other_seg_group * other_sel - OTHER_SEL_ALL, OTHER_SEL_ONSCREEN, or OTHER_SEL_GROUP * limit_to_group - True to filter by Group column * limit_group - Group index for filtering (comes from List if DATASOURCE_LIST, else from Segments table) * signals - SIGNALS_ALL, SIGNALS_SOURCE, or SIGNALS_CUSTOM * signals_custom * no_filter: False to use "Data Source" filter settings * subtract_fit - SUBTRACT_FIT_NONE, SUBTRACT_FIT_CURVE, or SUBTRACT_FIT_NODES * resample * resample_kHz * process - PROC_NONE, PROC_AVG, PROC_ADD, or PROC_SUB * process_sub_trace * process_all * path_expr * open_after

SIGNAL_MENU_HELP

Value:

'''Enter a list of signals, separated by semicolons ";"
For example:
  Current; Voltage
Instead of a signal name, you can define a function:
  I=Current; G=Current/((Voltage - (-60)) * 1e-3); V=Voltage
Or mix and match:
  Current; G=Current/((Voltage - (-60)) * 1e-3); Voltage
