04 Mar 2013	TDMS Reader Read TDMS files v1 & v2 without DLL Current Version: 2.5	Amrita	I get the following error when I try to read a tdms file: ??? Undefined function or method 'TDMS_handleGetDataOption' for input arguments of type 'struct'. Error in ==> TDMS_readTDMSFile at 216 TDMS_handleGetDataOption('check',paramsStruct) Error in ==> TDMS_getStruct at 57 [temp,metaStruct] = TDMS_readTDMSFile(filePath,readOptions{:}); How do I solve this? Thanks!	Comment only
01 Mar 2013	TDMS Reader Read TDMS files v1 & v2 without DLL Current Version: 2.5	Robert	I am trying to use the file to convert tdms file but I have a following error: Error using TDMS_preprocessFile (line 450) The remaining data doesn't split evently into chunks, estimated # of chunks: 8.181818e-01 Error in TDMS_readTDMSFile (line 226) metaStruct = TDMS_preprocessFile(fid,tdmsFileName,paramsStruct); Could someone help me to solve it, please?

22 Feb 2013	TDMS Reader Read TDMS files v1 & v2 without DLL Current Version: 2.5	Joe Cuschieri	I am using your algorithm posted on the MATLAB Central to read data from a TDMS file, however I am getting an error which I do not quite understand why. This is a section of my code: getStruct = struct; getStruct.group = {'6120'}; getStruct.channel = {'Untitled 3'}; getStruct.indices = [2 3]; tempOutput4 = TDMS_readTDMSFile(fname,'GET_INDICES',getStruct,'SUBSET_IS_LENGTH',false) However I get these errors: Error using cell/ismember>cellismemberlegacy (line 132) Input A of class cell and input B of class cell must be cell arrays of strings, unless one is a string. Error in cell/ismember (line 76) [varargout{1:nlhs}] = cellismemberlegacy(varargin{:}); Error in TDMS_handleGetDataOption (line 167) [~,loc] = ismember(objPaths_getIndex,objectPaths); Error in TDMS_readTDMSFile (line 228) optionStruct = TDMS_handleGetDataOption('getArray',paramsStruct,metaStruct); %Option handling Error in Test1 (line 21) tempOutput4 = TDMS_readTDMSFile(fname,'GET_INDICES',getStruct,'SUBSET_IS_LENGTH',false) I am using MATLAB R2012b. Any suggestions?	5
22 Feb 2013	TDMS Reader Read TDMS files v1 & v2 without DLL Current Version: 2.5	Jim Hokanson	René, TDMS doesn't contain time unless you explicitly save it as a channel. This is most often only done if you are sampling something periodically, such that the timing between events is not constant. Otherwise time is usually implied from a known sampling rate. If you are saving the time as a timestamp, I currently return the timestamp array as a numeric vector in Matlab's time format instead of converting each element to a string (like datestr). This makes it easier to do computations on the time (note that a difference of 1 in this vector represents a difference of 1 day, divide by 86400 to go to seconds). If you still have questions feel free to contact me via email. Jim	Comment only
