Corregistration error

Hi everyone,

I want to do a corregistration on 2 images and I am getting this error:

Error: [NodeId: Back-Geocoding] org.jblas.Nativeblas.dgemm(CCIID[DII[DIID[DII)V

I am on SNAP 8 and installed libgfortran3 and jblas for linux

my images are:

S1A_IW_SLC__1SSV_20150611T114943_20150611T115018_006325_008502_D47E_split_orb
S1A_IW_SLC__1SSV_20150623T114944_20150623T115019_006500_008A06_D4E6_split_orb

Is there any solution for this or should I go back to SNAP 7?

thank you very much
