kk,

can you send me your qdec.table.data? qdec automatically assigns a factor as a fixed fctor if it is not a number (as sscanf determines), so maybe there is a data point that is wrong.

hi,

i am trying to do group analysis in qdec...my fixed factor = gender; continuous factors= age, lhthickness and rhthickness

for some reason i am coming across two following issues over and over:

1- the qdec shows fixed factors are gender, lh thickness and rhthickness while covariate as age I did mention gender.levels file as female and male as per described in tutorial, but still it keeps showing me lh/rh thickness as fixed factor

2- out of 900 some subjects, it only picks 78 subjects and displays following:

ERROR: Subject 126921_005547 seems to have a mismatched number of continuous factors (expected 3, found 1) ERROR: Subject 126921_005547 seems to have a mismatched number of discrete factors (expected 1, found 3)

i checked my qdec.table.dat and it looks fine.....i used this command 'mac2unix' as i imported my data from csv to emacs.....

may i please know where am i heading wrong?
