|
directories |
Vector of paths to folder containing fasta files. Files in one folder should belong to one class. |
format |
File format. |
batch.size |
Number of batches, will get rounded to be multiple of number of targets if necessary. |
maxlen |
Length of predictor sequence. |
max_iter |
Stop after max_iter number of iterations failed to produce a new batch. |
vocabulary |
Vector of allowed characters, character outside vocabulary get encoded as 0-vector. |
verbose |
Whether to show message. |
randomFiles |
Logical, whether to go through files randomly or sequential. |
step |
How often to take a sample. |
showWarnings |
Logical, give warning if character outside vocabulary appears. |
seed |
Sets seed for set.seed function, for reproducible results when using |
shuffleFastaEntries |
Logical, shuffle fasta entries. |
numberOfFiles |
Use only specified number of files, ignored if greater than number of files in |
fileLog |
Write name of files to csv file if path is specified. |
reverseComplements |
Logical, half of batch contains sequences and other its reverse complements. Reverse complement
is given by reversed order of sequence and switching A/T and C/G. |
val |
Logical, call initialized generarator "genY" or "genValY" where Y is an integer between 1 and length of directories. |
