Repeated Measures data in spreadsheets

Dear Darinka,
This format of subjects in rows and scores in columns is what we are now using for the MEASURES, MORTABLE, and EVAL programs that output Excel-type tables. However, if you are creating various custom measures through special purpose runs on data, it is difficult for me to see how CLAN can guess the format of what you are creating. Maybe you are saying that you are creating a collection of separate files for each subject and then trying to cut and paste data from these separate files into a single file. But, in that case, maybe you should have run your command on *.cha using *CHI as the consistent identifier for your target child rather than "Peter" "Mary" and "John".
In any case, some of this can be done with what we already have and some cannot. It all depends on the details of how your data is coded, how subjects appear across files, and so on. In the end, sometimes it may just be necessary to resort to cut and paste. However, if there is some consistent and typical method that we can implement, we would try. But we would need to have it very closely described. Take a look at MEASURES, MORTABLE, and EVAL to get some sense of how this might work.
Best regards,

So, working for example in SPSS, we have to sort age samples into different columns like all other variables (utterances, morphemes, etc.), while participants should be sorted in rows like this:
