8 | This script uses the WLAN Exp Log framework to update version information |
---|
9 | in a given hdf5 log file that contains data assocated with an experiment |
---|
10 | utilizing the 802.11 reference design and WLAN Exp. |
---|
11 | |
---|
12 | Hardware Setup: |
---|
13 | - None. Updating log version information can be done completely off-line |
---|
14 | |
---|
15 | Required Script Changes: |
---|
16 | - None. Script requires filename of file to be anonymized to be |
---|
17 | passed in on the command line. |
---|
18 | |
---|
19 | Description: |
---|
20 | This script parses the log file and updates any WLAN Exp / 802.11 |
---|
21 | version information and write the resulting log data to a new file. |
