 ===Loading ASCII columns without header===
 When loading a multi-column ASCII files without header, the metadata of the signals are not available (see [[Geopsy: Database]]). Particularly, the sampling frequency (or time interval dt) is strictly required by Geopsy to create time series.  Therefore this information has to be added in the corresponding table field by [[Geopsy: Table#Table editing|editing the table]].
-Moreover, the sorting procedure applied when using any Geopsy [[Geopsy: Tools|Tool]] requires the Name of the station and the Component (especially for H/V processing). Without this information, since Geopsy is stacking the signals with the same Name and Component, all the traces will be stacked in the case of a ASCII column file without header that will not lead to the awaited results. Name and Component have therefore also to be added by [[Geopsy: Table#Table editing|editing the table]].
