weird results of otbcli_DimensionalityReduction (pca)

Description

Resulting PC image has striping. Observed in several different images.

Result very different from that obtained with R (RSToolbox::rasterPCA())

(in both cases, RGB composites of PC1,PC2,PC3)

Also, eigenvectors are different:
otb:
BertMICA20190531v2PCA.csv
R:
eigenvR.csv (note: eigenvectors in R by columns)

In both cases, input image has no data values set to 0:

Note: PCA for large images is impractical in R because it takes too long a time.

Steps to reproduce

otbcli_DimensionalityReduction.bat -in BertMICA20190531v2.tif -outBertMICA20190531v2PCA.tif uint8 -nbcomp 5 -normalize false -outmatrix BertMICA20190531v2PCA.csv -ram 128

Configuration information

otb 6.6.1 (same results on windows and linux)
