After execution of the M-File catman_read, the content of binary catman DAQ files are available in MATLAB. Two structured variables (one with global content, one with DAQ data) are delivered by the M-File.
Catman Online Data files are not supported.
Hint: This version is an unsupported version.
HBM can not give any support.
File versions of catman have changed and the newest versions are not supported.

Version 220.127.116.11 + @Daniel Waterman fix posted 1 Aug 2011 worked well with files from catmanEasy/AP version=18.104.22.168.
@Andreas, can you update the script?
I am trying to read a .bin file recorded using HBM equipment. I am getting the following error:
Error using fread
Error in catman_read (line 111)
Any advise on how to fix this.
Thanks in advance.
Issues observed working with more than 16 DAQ channels. Channels number higher than channel 16 are shown as empty.
HBM would like to make its own catman file importer available on the Matlab file exchange.
As soon as this is done, this Post will be deleted.
Thanks Daniel for the fix! Works with
Function seems to be working with the additions made by Daniel. There is a minor bug though concerning the formula information which is retrieved but then disregarded.
When lines 183-185 are changed to the following the formula is also saved to the channel information:
formula = setstr(fread(fid[1,Lf],'char'));
chaninfo.formula = formula(3:end); % Remove @@ for convenience
chaninfo.formula = '';
Working nicely for me, too with Daniel's mod. Thanks a lot!
Another confirmation Daniel's fix below works successfully.
CatmanEasy Version 22.214.171.124
Daniel's patch seems to work correctly for a file I've just received.
Without it headers decoded correctly but data is clearly incorrect.
As of version 3.2.1, Catman can export data to mat files. I don't know if Catman File Importer with the above fix works for versions above 3.1.11.
I am using Catman Easy 3.1.11 and this importer DOES work for new versions, but you need to make the following modifications to catman_read.m:
Change line 88:
dataoffset=fread(fid,1,'long'); % Offset in Byte from start of file for Data Area
Add line 195:
fseek(fid,a1.dataoffset,'bof'); % Jump file pointer to data area
I can't test it with data files from older versions of Catman, so can anyone verify that it works? I've contacted HMB and asked them to check as well. The author's email address at HBM appears to no longer be active.
As per version of Catman easy 3.1.1 the internal Catman data format is changed. This has not yet been reflected in a new version of catman_read
I have worked with the old version for a long time. It works flawlessly up untill now. After an upgrade of Catman easy the catman_read function delivers incorrect data. An upgrade of the function as per 26 April 2010 does not function because the zip file contains the old catman_read function dated at 4/22/2005. Should there not be a new version of the catman_read function?
just works. great!
makes it real easy to read catman files; real sweet!
