    DNA comparison: Repeated-measures ANOVA.. but too many parameters to consider?




    Dilemma about which test to correctly use... It's a tricky, confusing, one!
    I'm looking at DNA extraction methods, here's how I've got the data set up:
    Genotyped data from 80 fish, using 14 markers.
    So, for each fish, for 14 markers, theres two paired values per marker (2 alleles).

    However: then used 4 different methods of extraction on each fish to compare for quality.

    So, for each individual fish, there are 4 rows of data for each method... with each row having 14 markers of paired values.

    Anyone with me so far?

    Basically, I want to look to see if there are any differences between the values for each method.... I'm thinking repeated-measures ANOVA, but trying to take into account the paired values for so many different markers, with different methods, for different fish is tricky...

    Any suggestions on a test? I'm desperate and at my wits end trying different combinations.
    Plee for help

    Could you clarify your question? Clearly state what are your variables (type, how many) and what hypothesis are you trying to test.
