Currently I us the obspy **read** method to get the stats of the Reftek130 file, example:  
**data = read(archive\_file\_path,format=“REFTEK130”)**

```
		for i in range(0,len(data)):
			npts = data[i].stats.npts
			sr = data[i].stats.sampling_rate
			start_time = data[i].stats.starttime
			end_time = data[i].stats.endtime

```

This is understandably a slow method considering it is accessing the entire data block.  
Is there a faster way to retrieve only the file stats?  
Thank you

Please have a look at the documentation of `read()`. The `headonly` option might work for you.
