Hi Richard , In previous I forgot to mention a msscanf()'s detail to iterate , optional niter= -1 (until the end of file)
r8= msscanf(-1, txt(:,8), "NET: %3dx1 m3") // iterate on specific data fixed format, 8th column r1= msscanf(-1, txt(:,1), "%2d-%2d-%2d %2d:%2d:%2d") // timestamps decoding, 1st column David -----Message d'origine----- De : CHEZE David 227480 Envoyé : mercredi 10 mai 2023 12:00 À : 'Users mailing list for Scilab' <users@lists.scilab.org> Objet : RE: [Scilab-users] Need Help / Ideas on Log-File parsing More specifically : fchem="C:\Users\usr\Documents\scilab\TMP\data2impbzr.txt" // sample text file with your data txt= mgetl(fchem); //read lines txt(txt=="")=[]; //remove the empty lines txt=matrix(txt,17,-1)'; //reshape the matrix r8=msscanf(txt(:,8),"NET: %3dx1 m3") // for instance for 8th columns -----Message d'origine----- De : CHEZE David 227480 Envoyé : mercredi 10 mai 2023 11:33 À : 'Users mailing list for Scilab' <users@lists.scilab.org> Objet : RE: [Scilab-users] Need Help / Ideas on Log-File parsing Hi Richard, As first approach, i would read first whole file as vector of text lines, then keep only regular blocks of 17 lines: you got a matrix of strings size n*17 : throw every columns that you don't really need . Then parse separately the timestamp column with appropriate token to construct vector of times. Then, only for every columns vector of strings you are interested in, retrieve numerical values with csvTextScan for instance .

[snip] <file end> Which is an absolutely stupid format ... :-(, to make matters worst there is one log-file created per day and I want to log over one month of data. So far I have no idea how to takle this, because from what I see the usual msscanf and csvread expect data in row and columns. Any tip and ideas are welcome.
