problem creating pca object

[jawi005]

Hi Kevin,

I am using the latest version of PCAtools in R 4.2.2. I want to know how to solve this error.

this is my code

dds <- DESeqDataSetFromMatrix(expression, coldata, ~condition)
dds <- DESeq(dds)
vst <- assay(vst(dds))

p <- pca(vst, metadata = coldata[,1], removeVar = 0.1)

the error that occurs is

'colnames(mat)' is not identical to 'rownames(metadata)'

but if i check

rownames(metadata) == colnames(vst)

the result is TRUE

what am I doing wrong here?
Thanks for your help!
