How to calculate a running average in SAC.
2020-11-24 15:31:55 - 2020-11-26 14:10:42
Aloha, I found a command called “smooth” that will perform a running average. However, it does not work on my version of SAC [11/11/2013 (Version 101.6a)] running on OS High Sierra Version 10.13.6 on my 2018 MacBook Pro Any help on how I can run a moving average appreciated! Cheers, Barry

Bulk conversion of MiniSEED to SAC
2020-11-18 22:07:28 - 2020-11-21 19:03:22
Hi Everyone, I am new to this forum, but I am hoping someone can help me :) I am trying to convert ~10,000 individual MiniSEED files into SAC. I currently am able to do so one by one however this is insanely time consuming. I have the files all organized into annual folders 2014 - 2018. Is there any way to bulk process these for instance by folder. I am not a novice with Ubuntu and I feel like there must be a simple solution by someone who knows better. Thank you in advance for any… [more]

Hi, I keep getting an 'ERROR 1301: No data files read in.' message. I am using 'respknt' code written by G.Randall to calculate P & S wave response, which is written in detail in the following link. http://eqseis.geosc.psu.edu/cammon/HTML/RftnDocs/resp01.html I downloaded a set of codes including 'respknt' from Charles Ammon's website, which is as follows. http://eqseis.geosc.psu.edu/cammon/HTML/RftnDocs/thecodes01.html I followed all the instructions written in the link, and made a velocity… [more]

Discrepancy in the values in epicentral distance (km)
2020-10-30 13:52:20 - 2020-11-03 00:06:10
Hi, I have stations cross correlated files(.) with SAC headers. I found out the maximum and minimum values of epicentral distance (dist) is 418.29 and 10.24 respectively. but when I plot epicentral vs distance plot using GMT pssac, the plot comes up with a max and minimum value around ~425km and ~20km. It would be so great if you could give some suggestion regarding this. Thank you very much

Installation on MacOS
2020-11-01 21:00:28 - 2020-11-02 15:59:54
Hi IRIS, Thank you for sending SAC folder. I think I can open the SAC code manually by a zip open application. However, I cannot open it with the provided code for the terminal. Also, so sorry but I don't think I understand much the instruction for installation of SAC on MacOS, can you help me with a clearer installation instruction for SAC? Thank you so much. Best, Phuc Mach.
