gct_path <- system.file("extdata", "modzs_n25x50.gctx", package="cmapR")
# read the GCT file, getting the matrix only
g <- parse_gctx(gct_path, matrix_only=TRUE)
# separately, read the column annotations and then apply them using
# annotate_gct
cdesc <- read_gctx_meta(gct_path, dim="col")
g <- annotate_gct(g, cdesc, dim="col", keyfield="id")
