another question: i run seq-dim_(prifixspan+Apriori) on contextMDsequence wit min_sup=50% and take this output:
[ * * * ]{t=0, 1 } #SUP: 2
[ 1 * * ]{t=0, 1 } #SUP: 2
[ * * 1 ]{t=0, 1 } #SUP: 2
[ 1 * 1 ]{t=0, 1 } #SUP: 2
[ * * * ]{t=0, 2 } #SUP: 4
[ 1 * * ]{t=0, 2 } #SUP: 3
[ * * 1 ]{t=0, 2 } #SUP: 2
[ * 2 * ]{t=0, 2 } #SUP: 2
[ 1 * 1 ]{t=0, 2 } #SUP: 2
[ 1 2 * ]{t=0, 2 } #SUP: 2
[ * * * ]{t=0, 3 } #SUP: 3
[ 1 * * ]{t=0, 3 } #SUP: 2
[ * * * ]{t=0, 3 5 } #SUP: 2
[ * * * ]{t=0, 5 } #SUP: 2
[ * * * ]{t=0, 6 } #SUP: 2
[ 1 * * ]{t=0, 6 } #SUP: 2
[ * 2 * ]{t=0, 6 } #SUP: 2
[ 1 2 * ]{t=0, 6 } #SUP: 2
[ * * * ]{t=0, 2 }{t=0, 3 } #SUP: 3
[ 1 * * ]{t=0, 2 }{t=0, 3 } #SUP: 2
[ * * * ]{t=0, 2 }{t=0, 3 5 } #SUP: 2
[ * * * ]{t=0, 2 }{t=0, 6 } #SUP: 2
[ 1 * * ]{t=0, 2 }{t=0, 6 } #SUP: 2
[ * 2 * ]{t=0, 2 }{t=0, 6 } #SUP: 2
[ 1 2 * ]{t=0, 2 }{t=0, 6 } #SUP: 2
[ * * * ]{t=0, 2 }{t=0, 5 } #SUP: 2
what meaning of t in this output?
