Effect of the histone deacetylase inhibitor Trichostatin A on facial development in cichlid fishes

# Effect of the histone deacetylase inhibitor Trichostatin A on facial development in cichlid fishes [https://doi.org/10.5061/dryad.0zpc86746](https://doi.org/10.5061/dryad.0zpc86746) The files deposited in this repository were collected to examine the effects of a chemical treatment (Trichostatin A) on craniofacial morphology in Tropheops sp. "red fin" (Tropheops) and Maylandia zebra (Maylandia) during development. Each species was analyzed separately. Files named \_TPS files include ventral (named Species\_ventral) and lateral (named Species\_lateral) landmark data used for geometric morphometric shape analysis. \_PCscores.csv contain the principal component scores from the geometric morphometric analysis. The "Maylandia\_dev\_delay" files were collected to see if the effects of the Trichostain A treatment were causing a developmental delay in Maylandia. Timepoints are indicated in file and sample names based on days of cichlid development during which treatments occurred. That is, samples marked 2\_3 were treated from 2 dpf to 3 dpf (stage 10-11), 3\_4 is from 3 dpf to 4 dpf (stage 11-15) and 5\_6 is from 5 dpf to 6 dpf (stage 17-18) based on Fujimura & Okada, 2007.
