Hello, I am new to using tophat and bowtie for RNA-seq data. I am using MAC OSX10.11.4. I downloaded and unpacked the tophat2 binaries (ophat-2.1.1.OSX_x86_64). I also downloaded Bowtie2-2.2.9. I ran the test on the folder that is on tophat website (test_data) and I am getting the following error
dyn-172-20-71-206:test_data iyounis$ tophat2 -r 20 test_ref reads_1.fq reads_2.fq

[2016-05-11 11:37:55] Searching for junctions via segment mapping
[FAILED]
Error: segment-based junction search failed with err =-5
Reason: image not found
I checked the segment_juncs.log file and it reads the following:
dyld: Library not loaded: /usr/local/opt/boost/lib/libboost_thread-mt.dylib
Referenced from: /Users/iyounis/Desktop/RNA_seq_analysis/tophat-2.1.1.OSX_x86_64/segment_juncs
Reason: image not found
I downloaded tophat binaries because I didn't want to mess with boost, but I am not sure what to do next
Any help?
Shoot the tophat authors an email and let them know that they have a wrong library getting linked in.
I'm having this same problem now. Any resolution?
This problem still exists as of today; I got the same error.
I have the exact same issue. Has anybody been able to resolve this problem?
