Hi everyone, I am trying to plot FMS as per the instruction provided on pygmt web page. However, i did not get any result. Error message saying that my file is not in correct format. May someone suggest me how i can prepare a file including the label text for each FMS beach ball. ``` data=pd.read_csv("FMS.txt", sep='\s+') fig.meca(spec=data, convention='aki', offset=True, scale='0.3c', C=True) ``` [FMS.txt](https://forum.generic-mapping-tools.org/uploads/short-url/uhx6EGlRHo44Jl5Mf9bBj0pVbnV.txt) (280 Bytes) ---

Hello @Adnan, You have to use `longitude` and `latitude` for the columns names, instead of `lon` and `lat`. Futhermore it looks like you mixed up longitude and latitude for either the event location (colums `longitude` and `latitude`) or the plot location (colums `plot_latitude` and `plot_longitude`) in your FMS.txt file: ```auto longitude latitude depth strike dip rake magnitude plot_latitude plot_longitude 73.47 34.38 12.0 334 40 123 7.6 73.67 34.42 71.27 32.95 15.0 237 5 79 6 71.40 33.05 73.85 32.83 14.7 246 10 52 5.9 73.95 33.00 73.21 33.92 22.1 148 82 6 5 73.31 34.00 73.51 32.62 24.7 246 21 61 4.9 73.39 32.50 ``` To add labels to the single beachballs you need a column `event_name` containing the desired text: ```auto longitude latitude depth strike dip rake magnitude plot_latitude plot_longitude event_name 73.47 34.38 12.0 334 40 123 7.6 73.67 34.42 event_1 71.27 32.95 15.0 237 5 79 6 71.40 33.05 event_2 73.85 32.83 14.7 246 10 52 5.9 73.95 33.00 event_3 73.21 33.92 22.1 148 82 6 5 73.31 34.00 event_4 73.51 32.62 24.7 246 21 61 4.9 73.39 32.50 event_5 ``` ---

> [@Adnan](#): > > ```auto > data=pd.read_csv("FMS.txt", sep='\s+') > fig.meca(spec=data, convention='aki', offset=True, scale='0.3c', C=True) > > ``` Thanks for suggestions, It works well but only without the event label. For example, if i use the following format, it plots the FMS ```auto longitude latitude depth strike dip rake magnitude plot_longitude plot_latitude 73.47 34.38 12 334 40 123 6.4 73.85 34.75 ``` But when I add the event label, then error. ```auto longitude latitude depth strike dip rake magnitude plot_longitude plot_latitude event_name 73.47 34.38 12 334 40 123 6.3 73.85 34.75 m6-2010 ``` Plus, I also like to include direction from epicenter toward the source. ---
