model7: Empirical error model Roche/454 FLX Titanium, single-end read

In polyester: Simulate RNA-seq reads

Description

for each position in a single-end read generated with the specified chemistry, this data frame contains the probability of not making a sequencing error, and of making each of the 4 possible types of sequencing errors. The reference base (truth) is in column 1, and the probabilities of sequencing that base given its read position (column 7) as each of the 5 possible bases (A, T, G, C, and N) is given in columns 2 through 6, respectively. So for example, at position 8 in mate 1 of a read where the true base is C, the probability of correctly calling that base a C is 0.9994, the probability of making an error by sequencing a T is 0.0002, the probability of making an error by sequencing a G is 0.0001, the probability of making an error by sequencing an A is 0.0002, and the probability of reading an 'N' at position 8 is 0. This can be seen by looking at model7[model7$pos == 8,]. Note that position indexing is 1-based, though a 0 position is included as described in the GemSIM documentation.
