Hello I am getting this error while aligning sequences. I use Clusterize(), AlignSeq() and DistanceMatrix(). Clusterize works fine, but not the other two. There are about 50,000 sequences with range 50-200 base pairs each

How much memory is available on the computer? A distance matrix of 50k sequences requires at least 50k50k/2 8 bytes = 10GB, assuming the output
type = 'dist'
inDistanceMatrix()
.AlignSeqs()
(depending on the parameterization) will need more memory than the distance matrix. Please provide example code if you would like more assistance.
