I was running my first small set of data this week on the Windows version of Mothur 1.44.2 and found that my results seemed strange after the make.contigs(file=…, oligos=…, checkorient=t, pdiffs=0), so I installed a Virtual box with Ubuntu 16 to try the linux version. With the same command and the same file and oligos, I got a totally different results. Here is the result of the windows version:
