`exprsMat_test`	A list or a matrix indicates the log-transformed expression matrices of the query datasets
`trainRes`	A 'scClassifyTrainModel' or a 'list' indicates scClassify trained model
`cellTypes_test`	A list or a vector indicates cell types of the qurey datasets (Optional).
`k`	An integer indicates the number of neighbour
`prob_threshold`	A numeric indicates the probability threshold for KNN/WKNN/DWKNN.
`cor_threshold_static`	A numeric indicates the static correlation threshold.
`cor_threshold_high`	A numeric indicates the highest correlation threshold
`features`	A vector indicates the gene selection method, set as "limma" by default. This should be one or more of "limma", "DV", "DD", "chisq", "BI".
`algorithm`	A vector indicates the KNN method that are used, set as "WKNN" by default. This should be one or more of "WKNN", "KNN", "DWKNN".
`similarity`	A vector indicates the similarity measure that are used, set as "pearson" by default. This should be one or more of "pearson", "spearman", "cosine", "jaccard", "kendall", "binomial", "weighted_rank","manhattan"
`cutoff_method`	A vector indicates the method to cutoff the correlation distribution. Set as "dynamic" by default.
`weighted_ensemble`	A logical input indicates in ensemble learning, whether the results is combined by a weighted score for each base classifier.
`weights`	A vector indicates the weights for ensemble
`parallel`	A logical input indicates whether running in paralllel or not
`BPPARAM`	A `BiocParallelParam` class object from the `BiocParallel` package is used. Default is SerialParam().
`verbose`	A logical input indicates whether the intermediate steps will be printed
