# My SION files are HUGE! What can I do?
See [SION File Defragmentation](Usage#sion-file-defragmentation). Note that you can still load the defragmented SION file into python, see [Linktest Python Reader](Linktest-Python-Reader), and it can still be used to generate reports, see [Linktest Report](Linktest-Report). After defragmentation the file can be further compressed using any non-lossy compression tools. The resultant compressed file can no longer be loaded into python and hence reports based on it cannot be generated unless the file is decompressed first.
If you write out your SION files in parallel, which causes fragmented SION files to be written out, see [SION File Defragmentation](Usage#sion-file-defragmentation), otherwise only non-lossy compression can help you further.

# In Linktest Report (the python tool) I cannot read the indexed-image tick labels. Can I increase the font size?
You may be able to indirectly increase the font size. The font size is limited by two factors, the number of ticks, which limits the vertical height of the text of each tick, and the maximum length of each tick label. See the `--downsampling_factor_matrix_ticks` option in [the Linktest Report options](Linktest-Report#options) to learn how to reduce the number of ticks plotted, which increases the vertical space allocated to each tick label. See the `--domain` option in [the Linktest Report options](Linktest-Report#options) to earn how domains, or any string, can be removed from the tick labels. Shortening tick labels allows for larger font sizes for a given maximum tick-label width.

5. Use the supplied pingponganalysis tools. These create postscript files that can be converted to pdf. Generating a comparable PDF report to the above mentioned 2 minute report only takes about 5 to 10 seconds. Please note that the pingponganalysis tools are only kept up-to-date with the current version of Linktest.
6. Read the SION files directly into Python and inspect the data there using the [Linktest Python Reader](Linktest-Python-Reader). This does not substitute a nice and easy to read report but gives you the flexibility of looking at the data more in depth or to produce figures that better fit your needs.

# What do the weird unit prefixes, like ki, Mi and Gi, mean?
TLDR: They are binary prefixes.
