create_sots: textread deprecated

[MaurizioSicorello]

Matlab recommends not to use textread anymore (see snippet from create_sots below). Textscan would be an alternative. Another option would be to use readcell() to separately extract the variable names for the logfiles and the data extract the data. This way, it might be possible to subset the important variables by their names and not with complex formatting, which might go wrong if stimulus onset files are not identical (e.g., when they have a column for participant IDs at the beginning or not).

[event_type,event_code,event_time] = textread([logfile.folder,filesep,logfile.name],'%*d %s %s %d %*s%*s%*s%*s%*s%*s%*s%*s%*s','headerlines',IgnoreHeaderLines)
