Overview
This document lists the various tools for working with uwar files and related data. An example .uwar file is hosted on this machine that you can use to test with. Most of the outputs on this page are from this file: example.uwar.
parse_uwar_dir
- msp/uwar_stats/parse_uwar_dir.cpp
- linux download (x86)
- windows download
- windows download (required libsndfile.dll)
parse_uwar_dir replaces uwarToMatlab and converts data into binary data blobs called sensorName.bin and metaData files called sensorName.meta. The meta data files are of the format:
"NumSamples",47013 "SampleRate",512.000000 "Name","accelMag" "DataType",1 "firstTimestamp",0.000000 "lastTimestamp",91.820313
Where DataType is defined as:
case 1
DataType_string = 'single';
DataType_size = 4;
case 2
DataType_string = 'double';
DataType_size = 8;
case 3
DataType_string = 'int8';
DataType_size = 1;
case 4
DataType_string = 'uint8';
DataType_size = 1;
case 5
DataType_string = 'int16';
DataType_size = 2;
case 6
DataType_string = 'uint16';
DataType_size = 2;
case 7
DataType_string = 'int32';
DataType_size = 4;
case 8
DataType_string = 'uint32';
DataType_size = 4;
case 9
DataType_string = 'int64';
DataType_size = 8;
case 10
DataType_string = 'uint64';
DataType_size = 8;

uwar_cat
- msp/src/fileio/uwar-cat.c
- linux download (x86)
- windows download (does not support shared memory streaming)
uwar_cat is a program to extract data from uwar files and dump them in a human readable format. The output format is something of the form:
SENSORA TIMESTAMP DATA ... SENSORB TIMESTAMP DATA ... SENSORC TIMESTAMP DATA ...
If you want to retrieve data from a specific sensor you can use the grep command.
Windows users: You can download a win32 version of grep from the gnuwin32 webpage. You will also need to grab some additional libraries or you can try this zipped version which should contain all the necessary libraries. Simply extract the zip to your Windows\system32 directory.

uwar_msb_dump
- msp/src/fileio/uwar_msb_dump.c (not yet committed to CVS)
- linux download (x86)
- windows download
uwar_msb_dump is a program to dump the raw serial packets stored inside the uwar file to a single binary output file. This is useful for debugging problems with the MSB itself and analyzing the packets received by the msb-server.
usage
uwar_msb_dump <input_uwar_filename> <output_binary_file>

uwar-clean
- msp/src/fileio/uwar-clean.c (not yet committed to CVS)
- linux download (x86)
- windows download
uwar_clean removes corrupted packets from a .uwar file and stores the cleaned stream in a new file. Note, this program is based off of uwar-info so any file uwar-info can process it should be able to handle. It does NOT clean bad data inside a valid uwar packet.
usage
uwar_clean <input_uwar_filename> <output_cleaned_uwar_filename>
Note: Be careful not to specify the same input/output name as this will immediately erase your file. Remember if you say something like 'uwar_clean myVeryImportantData.uwar ./myVeryImportantData.uwar' you will likely lose your data!

- not available for xscale
- linux download (x86), ~8.2MB
- windows download (.zip), ~6MB
This program can be used to process and combine multiple .uwar files into more usable output formats. You should only pass in .uwar files that belong to a single recording run from a single device (you should only try to combine files that are uninterrupted recordings). The program will sort your input files for you; however, if it is unable to find an ordering without significant gaps it will reject the sequence. You can use the '-maxGap_sec' argument to increase the allowable gap.
Note these files contain the paths of the source files used to create them (e.g. 'C:\someData\log.uwar') so avoid using anything embarrassing or anything that causes any privacy concerns.
- completeSensorAudio.wav
- is a wav file created from the sensor board audio file with any missing samples filled in
- dataOut.mat
- is a Matlab file containing a struct with the sensor data in a timestamp, data format
- completeData.mat
- is a Matlab file containing a struct with the sensor data placed into fixed sample rate arrays. For example a sensor with a 100Hz sample would have 1 second of data represented by a 100 element array, and a corresponding time array with the start/end time: [0 1.0] (seconds).
- sirfBinaryOutput.bin
- is a binary file containing the serial stream from the sirf GPS unit
Matlab notes
Since uwarToMatlab uses Matlab to output its .mat files you need several .dlls to run the program. If you have the Matlab Component Runtime installed you don't need the associated .dlls in the .zip file (as they will have been added to your path during the MCR install process). If you are using Linux you should have the MCR installed or you can use the libraries included in the .tgz. Note that you may need to set your LD_LIBRARY_PATH to include the directory with the extracted .so files.
usage
Typical Usage
To combine two .uwar files and dump them into another target directory:
uwarToMatlab log-0001.uwar log-0002.uwar -outputdir "C:\temp\target"
Remember, uwarToMatlab will only try to combine the .uwar files you give it. If it believes the files shouldn't go together it will exit, if you are missing any files it will either quit or there will be large gaps in the data, and if you run it on multiple .uwar files with the same output directory it will erase the files it creates, not append to them.
Available Commands
uwarToMatlab [-options] <input file(s)>
[-outputdir N]
Create all output in directory N rather than the inferred directory
(Default behavior is to figure out the path from the first input file)
[-NoDataOut]
Do not create a dataOut mat file
[-NoCompleteData]
Do not create a completeData mat file
[-NoWavFile]
Do not write a completeSensorAudio.wav file
[-buffSize N]
Read buffer size in bytes (default 200k)
[-maxGap_sec N]
Maximum gap between .uwar files (in seconds, default 50*60)
[-disableChecks]
Disable header comparisons for uwar files, may result in corrupt files
[-ignoreRollover]
Ignore roll over events that appear to be errors and continue
[-printProgress]
Print progress of the parser every printProgressMax packets (default 10,000)
[-printProgressMax N]
Print progress of the parser every N packets (default 10,000)
[-blacklist file.txt]
List of uwar packet numbers to ignore
[-write_timestampFile]
Write the uwar packet #, time_counter, and interrupt_counter to a file 'timestamp.txt'
[-integerOutput]
Write the integer output from the msb2 parser instead of the double output
[-write_summaryFile]
Write some summary information to an <input file>.stats file
example output
-
There are a couple of notes about the output of the program:
- Text output:
- #INFO lines are supplemental information
- #WARNING lines contain non-critical errors
- #ERROR lines contain information about fatal processing errors.
- Warnings about missing samples are ok so long as the table at the end shows relatively little lost data. uwarToMatlab currently doesn't have any threshold for rejecting files containing too many missing samples.
- When a file error is encountered the program enters a "UWAR Error mode" where it searches the .uwar datastream for a new packet. This should typically only require a 1 byte search, resulting in 0 bytes skipped. However, it is possible for a file to be severly corrupted and this search may skip a large number of unrecoverable samples.
- The table printed at the end of the run contains summary information about the samples found, be sure to check that the file contains the appropriate samples and is for the most part correct.
