smfishHmrf.generate.centroid.save: Save the cluster centroids to file
In smfishHmrf: Hidden Markov Random Field for Spatial Transcriptomic Data

This function is run after the kmeans step. It takes a kmeans object (containing the kmeans result) as input and save the cluster centroids to file.

Note that the location of saving and the file names are decided by the following rule:

{output_dir}/k_{par_k}/f{name}.gene.ALL.centroid.txt
{output_dir}/k_{par_k}/f{name}.gene.ALL.kmeans.txt

where {} refers to the value of parameters.

1	smfishHmrf.generate.centroid.save(kk, name = "test", output_dir = ".")

`kk`	kmeans object
`name`	name of the run
`output_dir`	output directory; where to save the results

expr_file = system.file("extdata", "ftest.expression.txt", package="smfishHmrf")
y<-smfishHmrf.read.expression(expr_file)
kk = smfishHmrf.generate.centroid(y, par_k=9, par_seed=100, nstart=100)
smfishHmrf.generate.centroid.save(kk, name="test", output_dir=tempdir())
