IOError Errno 28 No space left on device

IOError: [Errno 28] No space left on device

Problem:

/tmp/ directory might be too small (for many samples or large sequence reference database)

Solution:

create new bigger directory for temporary files and tell path to qiime (a) and python (b)

(a) add path to QIIME default setting file .qiime_config

(b) for python, set path to shell variable TMPDIR (add command to your .bashrc file)

export TMPDIR=/my/new/tmp/directory
