Alright! I think it is installed. I have avoided using fastx-toolkit because it is such a pain in the butt to install, but alas, the uncertain has become certain. Why am I doing this? Because I am getting these alarming warning messages while Trinity is running. It seems to carry on regardless but it doesn't seem right.

...

warning: ignoring read XXXX since it cannot decipher if /1 or /2 of a pair.

Error: note that there were 4329123 reads that could not be deciphered as being /1 or /2 of a PE fragment. Hopefully, these were SE reads that should have been ignored. Otherwise, please research this further.

Okay, awesome. Seems like someone else ran into this problem:

http://sourceforge.net/p/trinityrnaseq/mailman/message/31448854/

After looking at what my input files were before and after trimming, it is clear that the fastq files have lost track of being from the right or left pair. Uggh! I knew that girl's Trinity help was too good to be true.

For once something worked. Oh yeah, just as a side note if you have illumina reads you must put -Q 33 parameter. This of course, is an undocumented fix discovered by users. Three+ years after this discovery, -Q remains to be documented in the fastx-toolkit. 

I still am going to do the pair matching before running trinity again.

----------------------------------------------------------------

Yay! I fixed the /1 /2 problem. You can see that the fasta files trinity creates there is now the /1 and /2. Now we will see if we can get past chrysalis and if the other error with the c++libs is fixed.

To be continued.

There doesn't seem to be a lot of resources troubleshooting this error for Trinity.  Because we are running it on a Mac OSX and Trinity is compiled only for Linux, there is no real support from the Trinity side of things. It may be possible that we are missing libc++abi. This is not a minor undertaking and takes about 24 hours to download, configure, build, and compile. Despite this terrifying error message:

Mac users, remember to be careful when replacing the system's libc++. Your system will not be able to boot without a funcioning libc++.

I will carry onwards.

Okay done. Let's hope I didn't break break the computer and let's see if this actually did anything.

Fail.

This is to be continued. At least they put a frowny face in the error message. 

Here is a blog that gives excellent Trinity instructions:

Everything is up and running now. Stay tuned.

Okay we have FINALLY updated our operating system.

Apparently Mavericks already has commandline tools installed so it is not necessary to install again. However, there are some issues if you install Homebrew and the gcc compiler not being linked. So starting from scratch, here is what do do.

#install homebrew

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

#check to see your comp is ready to brew

brew doctor

#i had several errors/warnings (errors indicated in orange)

/usr/bin comes before /usr/local/bin

export PATH='/usr/local/bin:$PATH' >> ~/.bash_profile

/usr/local/lib/gcc is not writable.

sudo chown -R laurelyohe /usr/local

brew install homebrew/science/bowtie

brew install apple-gcc42

brew install samtools

brew install trinity

Okay, everything seems good to go. Now I am unzipping the transcriptome output from trimmomatic.
