Theold listserver mailing list is no longer being supported by EBI. The new mailing list for issues relating to both GMAP and GSNAP is now at Google Groups. To sign up, go to your list, select "All groups and messages", and search for "gsnap-users". Click on that group, and then "Join group". You can join there to receive release notices, ask questions, or see previous messages. If you have a bug to report or a feature to request, I believe you can also send email to

You can build your own genome database with the gmap_build program included with this software. Please see instructions in the README file. For the human genome, you may want to retrieve UCSC hg19/GRCh37 Ensembl GRCh37

Sold mine within 5 swings of using it. The amount of bow it takes me to get it to snap was not feasible. Additionally, I noticed when I did get it to snap, I was extremely laid off and I do not like being laid off.
The Tac Tic or Power Click do not teach the lead wrist to go into flexion. Both of those training aids prevent the lead wrist from going into extension. Flexion is becoming more and more popular on tour with the likes of DJ, Rahm, Morikawa etc... There is no other training aid that teaches the lead wrist to go into flexion. In addition it is very adjustable and can snap with slight flexion to severe flexion based on what settings you have the device on. If you struggle leaving the face open on the downswing then this will help square the face sooner and make you rotate your body more. There are several PGA Tour players, LPGA Tour players and college golfers using it currently. It is a great product
Unless a golfer has a weak lead hand grip, it is very difficult to go into lead wrist flexion at impact . Dustin Johnson , who has a strong lead hand grip and off the scale mobility is the noticeable exception .Both Rahm and Morikawa have weak lead hand grips .
For me it is a great product. It helps me flight all of my clubs to a more efficient trajectory and less curve. I gained around 15 yards on my good drives by using that feeling and am much more consistent throughout my bag.
If you want to give it a shot before buying, get a slap wrist bracelet (from the 90s), slip it under a watch/silicon bracelet and your glove. It must be similar-ish, but I don't live in the states so it'd be super pricey to ship for me.
I was skeptical but knew that I was having club face issues. I found it difficult to get a snap even though my wrist looks flat on video @ top of backswing. Even harder to get it not to snap again before impact. But even the intention to make it snap in transition and not snap before impact did help clean up the clubface. Contact as more crisp and start line was much better. I am really struggling to apply it to driver, much easier with wedges and short irons thus far. Broke par for the first time this season after a long session with it.
I can only speak to the Trail Hand G-Snap as I await the lead hand one to come in the mail. As someone who always thought cocking both hands up was the way to control the face, I didn't realize how poorly I used my right hand in the backswing and how open my clubface could get without manipulation. Trail Hand G-Snap is up there with the stack system as one of the better swing training devices, if you have that issue. The best part of it is that I can play a round with it so you can have that bridge from range to course.
The second thing I love about it is the instant audio feedback. You can mess around at different points in your swing and if you really want to, use a speed radar to find out where you generate the most speed. I have been on a quest to changing my swing from a very handsy powerful swing to a more repeatable rotation swing and I believe these training aids will get me there much quicker.
I'm late to the party, but I just had a lesson with Casey Harty, whose coach is Gankas. I used the G-snap to help me with shaft lean and correct face position. It helped me immensely to feel the correct flexion in my lead wrist. Where I would have a correct face position on left arm parallel on my backswing, it would open at the top which would cause me to scoop/flip at impact. Using the G-snap is helping me correct that face position and the difference is night and day. I am going to purchase one and work with it for a few weeks and go back for another lesson. Just from first hand experience and with the problem I was having, it seems like a no brainer.
Any update on how it is going? I have been using tour striker planemate and like it but having difficulty still on the course and I suspect a lot has to do with bowing my wrists at the top and coming over the top rather than shallowing. Not an issue on short irons but major issues getting power on fairway woods and long hybrids. Cutting across the ball on contact.
I'm coming in way late here but i've been working on "holding the tray" so to say with the trail hand and having a lot of success but it's very sporadic getting it to lock in. Been looking at the prosendr and gsnap trail hand device, i know this thread was about the original gsnap but has anyone found more success with the trail hand device he released?
Hi, i needed some help. I wanted to download gsnap as an auto tune plugin but mixpad refuses to find it. I am not too tech savvy and would love some help from a professional willing to take it step by step with me. The problem i think is that mixpad does not want to find the path or somthing... If the problem is with gsnap, and someone knows a better software for pitch correction, I am open to new programs... THANKS
I followed these instructions exactly and MixPad still won't find GSnap. I have my VSTplugin folder in my Program Files. Does it matter where the folder is located or what it's named as long as the path is correct? Yes, I do have masters.
GSNAP is designed to align short reads from NGS data and allow detection ofshort and long range splicing de novo or with a database of know juctions. Inaddtion, SNP-tolerant alignements and alignments of reads obtained frombisulfite treated DNA are implemented.
in a structure analogous to the igenomes package. In addition, commonly usedgenomes are also available at/fdb/gmap_post20210308/common_genomes. This path is also thedefault path gmap and gsnap use to look for genome files, so a particular genomeis available there it is sufficient to provide the genome name with -dgenome_name to any of the tools without also specifying the genomedirectory with -D.
Gsnap throughput was measured using different numbers of threads with anENCODE data set (100nt single ended RNA-Seq, mouse Purkinje cells; accession ENCFF220BOE; biosample ENCSR758TAD). Discovery of novel splice sites was disabled but knownsplice sites were provided as input. The input file was compressed and storedon local scratch space. The output was saved unmodified on local scratch space. Eachprocess was allocated 30GB of memory. The exact command used was
The lower throughput of version 2015-05-01 with default settings is largely the result of a change in the default for one setting ( --end-detail) from medium to high which has the effect of improving alignments in the small number of cases where the distal end of a splice or indel contains a mismatch. Changing this version back to medium recovers most the loss in throughput. It is therefore largely a tradeoff between throughput and sensitivity. As of version 2016-06-30, the default reverted to medium.
Gsnap scales well with the number of threads all the way to 32, though the mostefficient use is probably around 24 threads with this input data set. Note that gsnap does not start any extra processes or threads, so --nthreads=$SLURM_CPUS_PER_TASK is appropriate unless the output ispiped into another process such as samtools. In that case the number of threads usedby the second process has to be subtracted from the number of threads given togsnap.
