Describe input parameters Two text files are required as input for analysis of each vertical succession of strata in the following formats.

Vertical thickness and facies succession: <unit thickness (m)> <facies code (integer)> <unit thickness (m)> <facies code (integer)> ... <unit thickness (m)> <facies code (integer)> EOF

e.g. 0.61 9 0.05 5 0.52 1 ... 1.21 3

Facies codes, colour coding and names: <Facies code 1 (integer)> <red (float)> <green (float)> <blue (float)> <facies name (string)> <Facies code 2 (integer)> <red (float)> <green (float)> <blue (float)> <facies name (string)> ... <Facies code n (integer)> <red (float)> <green (float)> <blue (float)> <facies name (string)>

e.g. 1 0.55 0.32 0 clay 2 1 0.65 0 silt 3 0.93 0.91 0.8 fineSST 4 1 0.95 0.71 medSST 5 0.81 0.71 0.23 crsSST

Input format ASCII

Describe output parameters Outputs are m and r values, plus p values indicating the probability that the calculated m and r values could occur by chance. Graphical output is produced showing the vertical section of strata, a transition probability matrix for the facies, a histogram of facies frequency, a plot of the m value calculated from observed strata versus the m values calculated from Monte Carlo modelling of shuffled equivalent strata, and a plot of the r value calculated from observed strata versus the r values calculated from Monte Carlo modelling of shuffled equivalent strata.
