This error appears if my output file is at /mnt/...(drive). But if an output file is in home directory - trinity runs well And some strange situation, when I wrote *sudo" the program cannot find salmon, but without this one, it runs well. When i run trinity i have the next error:

I guess the account you are running this from does not have write permissions to the mounted directory (/mnt/lapd/Vika_data/Denovo/trinity3/insilico_read_normalization/).

Is the drive filesystem NTFS or exFAT?

Hello,

I have the exact same issue when trinity-2.4.0 runs from vdjpuzzle- version 3.

Trinity does not work with NTFS, FAT32 partitions.

The reason for the error you are seeing is very likely that the Windows filesystem (NTFS or FAT32) on the mounted partition (/mnt/lapd/) does not support symbolic links. The solution is simple: When running Trinity under Linux, do not attempt to run Trinity on the mounted external hard drive, USB stick, etc. on which you received the data directly. Instead make a copy (including backup, should do that anyway) of the data to a directory within a "proper" POSIX-compliant file-system, e.g. easiest to your home directory or group network volume or a scratch disk attached to your server or workstation that has a Ext4, ZFS, XFS, etc. file-system. If you do not have enough space, you need to purchase a hard drive that you will create a partition on and format as Ext4 using Linux tools and copy the data to it.
